SAFETY CONSIDERATIONS
1.1
Electric Shock Hazard
Electrical shocks due to faulty mains driven power supplies.
Whilst ever potentially present in any electrical equipment, such a condition would be
minimised by quality installation practice and thorough testing at:
a) Original assembly.
b) Commissioning.
c) Regular intervals, thereafter.
All test equipment to be in good working order prior to its use. High current power supplies
can be dangerous because of the possibility of substantial arcing. Always switch off during
disconnection and reconnection.
1.2
RF Radiation Hazard
“CAUTION: This equipment is approved for antennas mounted on fixed outdoor permanent
structures. A minimum separation distance of 2 metres must be maintained between the
radiating elements and any nearby persons. A maximum antenna gain of 21 dBi may be used.
Operating this equipment without regard to these restrictions will result in RF exposure levels
above the limits allowed by FCC rules.”
This equipment complies with part 90 of the FCC rules. Any changes or modifications not
expressly approved by the manufacturer could void the user’s authority to operate the equipment.
RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to
AFL’s equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or because a ‘spare’
output has been left unterminated. Either of these conditions would impair the system’s
efficiency. No investigation should be carried out until all RF power sources have been
removed. This would always be a wise precaution, despite the severe mismatch between the
impedance of an N type connector at 50? , and that of free space at 377? , which would
severely mitigate against the efficient radiation of RF power. Radio frequency burns could also
be a hazard, if any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both local & statutory)
regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is
capable of producing RF field strengths, which may exceed guideline safe values especially if
used with antennas having appreciable gain. In this regard the use of directional antennas with
backscreens and a strict site rule that personnel must remain behind the screen while the RF
power is on, is strongly recommended.
Where the equipment is used near power lines, or in association with temporary masts not
having lightning protection, the use of a safety earth connected to the case-earthing bolt is
strongly advised.

1.3
Chemical Hazard
Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™ , is sometimes used in
devices within equipment produced by Aerial Facilities Ltd. Beryllium oxide dust can be toxic
if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by contact.
Products that contain beryllium are load terminations (dummy loads) and some power
amplifiers. These products can be identified by a yellow and black “skull and crossbones”
danger symbol (shown above). They are marked as hazardous in line with international
regulations, but pose no threat under normal circumstances. Only if a component containing
beryllium oxide has suffered catastrophic failure, or exploded, will there be any danger of the
formation of dust. Any dust that has been created will be contained within the equipment
module as long as the module remains sealed. For this reason, any module carrying the yellow
and black danger sign should not be opened. If the equipment is suspected of failure, or is at
the end of its life-cycle, it must be returned to Aerial Facilities Ltd for disposal.
To return such equipment, please contact the Quality Department, who will give you a
Returned Materials Authorisation (RMA) number. Please quote this number on the packing
documents, and on all correspondence relating to the shipment.
PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite Materials
Many modules/components in AFL equipment contain P.T.F.E. as part of the RF insulation
barrier.
This material should never be heated to the point where smoke or fumes are evolved. Any
person feeling drowsy after coming into contact with P.T.F.E. especially dust or fumes should
seek medical attention.

OVERVIEW/SYSTEM DESCRIPTION
The AFL Fibre feed Amplifiers for the Pasadena Blue line project are 2 way on-band RF
amplifiers. Their application is as an interface between the fibre optical link from the off air
amplifiers and the tunnel antenna/leaky feeder system. There are two units one designated
‘UNIT 1’ for the frequencies in the 470-473MHz range , the other ‘UNIT 2’ for the
frequencies in the 483-486MHz range.
Each unit is housed in an environmentally protected IP65 steel wall-mount case. Handles are
provided for carrying the unit and the door is fitted with locks. The unit interfaces with ‘N’
type female connectors for RF connections and heavy duty connectors for routing of AC
power supply input and alarm output wiring. Cable glands are provided for routing of the
Fibre optic cable in to the unit.
To provide adequate selectivity in the Downlink and Uplink paths, combline design duplexers
are used at the input and output ports. To provide the required gain to reach the required
signal levels, low-noise amplifiers (LNA’s) are used in each path, these being followed by
power amplifier modules in the uplink to provide the required intermodulation performance.
Gain adjustment is available locally using switched attenuators.
Note that “Downlink” refers to the RF path from FO receiver to the leaky feeder port and that
“Uplink” refers to the RF path from the leaky feeder port to the FO transmitter.
The AFL 800MHz Off Air Amplifier for the Pasadena Blue line project is a 2 way on-band RF
amplifier. It’s application is as an air interface between the donor radio site and the tunnel
leaky feeder system. Each unit is housed in an environmentally protected IP65 steel wallmount case. Handles are provided for carrying the unit and the door is fitted with locks. The
unit interfaces with ‘N’ type female connectors for RF connections and heavy duty connectors
for routing of AC power supply input and alarm output wiring.

5.1.1 Bandpass Filters (02-007302, 02-013401)
5.1.1.1
Description
The bandpass filters are multi-section designs with a bandwidth dependent upon the
passband frequencies, (both tuned to customer requirements). The response shape is
basically Chebyshev with a passband design ripple of 0.1dB. The filters are of combline
design, and are carefully aligned during manufacture in order to optimise the insertion loss,
VSWR and intermodulation characteristics of the unit. The tuned elements are silverplated to reduce surface ohmic losses and maintain a good VSWR figure and 50? load at
the input and output ports.
No adjustments should be attempted without full network sweep analysis facilities to
monitor both insertion loss and VSWR simultaneously.

5.1.2 ¼Watt 0- -30dB Switched Attenuator (10-000701)
5.1.2.1
General Application
In many practical applications for Cell Enhancers etc., the gain in each path is found to be
excessive. Therefore, provision is made within the unit for the setting of attenuation in
each path, to reduce the gain.
5.1.2.2
Switched Attenuators
The AFL switched attenuators are available in two different types; 0 – 30dB in 2 dB steps
(as in this case), or 0 – 15dB in 1 dB steps. The attenuation is simply set using the four
miniature toggle switches on the top of each unit. Each switch is clearly marked with the
attenuation it provides, and the total attenuation in line is the sum of the values switched
in. They are designed to maintain an accurate 50? impedance over their operating
frequency at both input and output.
5.1.3 Low Noise Amplifiers (11-006102, 11-007302 & 11-007402)
5.1.3.1
Description
The low noise amplifiers used are double or triple stage solid-state low-noise amplifiers.
Class A circuitry is used in the units to ensure excellent linearity over a very wide dynamic
range. The active devices are very moderately rated to provide a long trouble-free working
life. There are no adjustments on these amplifiers, and in the unlikely event of failure then
the entire amplifier should be replaced. Note that all three amplifiers use similar DC power
circuit boards.

5.1.4 3 Stage Amplifier Alarm Boards (12-002201)
5.1.4.1
Description
Amplifier Alarm Boards are fitted to monitor the bias conditions of AFL Class A amplifiers
which remain constant in normal operation. Any departure from normal bias conditions is a
result of device failure, excess temperature, over-driving or oscillation (excessive power).
In normal operation, the Class A bias circuit of the amplifier develops a constant voltage of
1.20V across the collector current setting resistor. The Amplifier Alarm Board is a window
comparator device, which is adjusted to sense a departure from this condition. Several
different alarm outputs are provided to simplify interfacing, (Relay Contact, Open Collector,
and TTL Logic Levels)
The basic version of the Alarm Board (12-002801) monitors a single amplifier stage. A threestage version (12-002201) is used on complex amplifiers where three separate comparators
have their outputs logically combined to a common output stage. Failure of any one stage will
activate the alarms.
Note that the alarm board has a green Light Emitting Diode located near to the centre of the
printed circuit board, which is illuminated on ‘Good’, and extinguished on ‘Alarm’. It is
therefore a simple matter to identify an active module failure, by searching for an Alarm
Board which has its green LED extinguished. A simple test of the alarm board is possible by
shorting across the monitor inputs, pins 1 and 2, 3 and 4 or across pins 5 and 6. This last
monitor input is inactive if the board has been converted to a two way alarm board. (Refer to
relevant amplifier alarm wiring diagram.)
1) Volt-free change over relay contacts.
2) Open collector NPN transistor pulls low on alarm.
3) TTL driver.
The use of precision voltage sources and resistors has eliminated the need for initial
adjustment or calibration, and the board will function correctly with a wide variation in power
supply voltage (8 to 30 volts, nominal supply is 12 or 24Volts).
There are two selectable link options on the three-way board:
LINK1
LINK2
- Removed to convert to two-way alarm board.
- Removed to isolate 0V from chassis earth.
The one way alarm board only has the 0V isolation link (LINK2) fitted.

5.1.5 10 Watt Power Amplifier (12-004205)
5.1.5.1
Description
The power amplifier fitted in this unit is a multi-stage, solid state power amplifier. Class A
circuitry is employed throughout the device to ensure excellent linearity over a wide
dynamic frequency range. All the semi-conductor devices are very conservatively rated to
ensure low device junction temperatures and a long, trouble free working lifetime.
The power amplifier should require no maintenance over its operating life. Under no
circumstances should the cover be removed or the side adjustments disturbed unless it is
certain that the amplifier has failed; since it is critically aligned during manufacture and any
re-alignment will require extensive test equipment.

5.1.6 DC/DC Converter, 24V in, 12V 8A out (13-003011)
5.1.6.1
Description
The DC/DC converter fitted is an AFL assembled, high power PCB unit with an 8 amp @
12V output capability. The circuit is basically an O.E.M semiconductor regulator (one side of
which has a heatsink mounting plate, that is usually bolted to the casing of a Cell Enhancer)
and smoothing components built onto a printed circuit board with screw block terminations.
Note: no circuit diagram of the O.E.M. regulator is available. This unit should not be
repaired, only replaced.

5.1.7 Wide Dynamic Range AGC (17-001101, Det. & 17-001201, Atten.)
5.1.7.1
Description
The equipment is fitted with a wide dynamic range Automatic Gain Control (AGC)
system. This is generally fitted in the Uplink path (not usually needed in the downlink path,
as the signal here is at an almost constant level), to avoid overloading the amplifiers (with
the associated performance degradation) should a mobile be operated very close to the
unit.
The AFL wide dynamic range Automatic Gain Control system consists of two units, a
detector/amplifier and an attenuator. The detector/amplifier unit is inserted in the RF path
on the output of the power amplifier, and the attenuator is situated in the RF path between
the 1st and 2nd stages of amplification.
Normally the attenuator is at minimum attenuation. The detector/amplifier unit monitors
the RF level being delivered by the power amplifier, and when a certain threshold is
reached it begins to increase the value of the attenuator to limit the RF output to the
(factory set) threshold. Therefore overloading of the power amplifier is avoided.
The factory set threshold is 1dB below the Enhancer 1dB compression point. Some
adjustment of this AGC threshold level is possible, a 10dB range is mostly achieved. It is
not recommended under any circumstances to adjust the AGC threshold to a level greater
than the 1dB compression point as system degradation will occur.
The detector comprises of a 50? transmission line with a resistive tap which samples a
small portion of the mainline power. The sampled signal is amplified and fed to a
conventional half wave diode rectifier, the output of which is a DC voltage proportional to
the RF input signal.
This DC voltage is passed via an inverting DC amplifier with integrating characteristics, to
the output, which drives the attenuation control line of the corresponding AGC attenuator.
This unit is fitted at some earlier point in the RF circuit.
The unit contains a 12V DC regulator in the detector module, which supplies stabilised
voltage to the DC amplifier and via an external cableform to the AGC attenuator.

For small signals, below AGC onset, the output control line will be close to 12V and the
AGC attenuator will have minimum attenuation. As the signal level increases the control line
voltage will fall, increasing the attenuator value and keeping the system output level at a
constant value.
The AGC onset level is adjusted by the choice of sampler resistor R1 and by the setting of
potentiometer VR1.
The attenuator comprises a 50? P.I.N diode, voltage-variable attenuator with a range of 3 to
30dB. The attenuation is controlled by a DC voltage which is derived from the associated
AGC detector unit.

5.1.8.1
Description
The General Purpose Relay Board allows the inversion of signals and the isolation of
circuits. It is equipped with a single dual pole change-over relay RL1, with completely
isolated wiring, accessed via a 15 way in-line connector.
The relay is provided with polarity protection diodes and diodes for suppressing the
transients caused by "flywheel effect" which can destroy switching transistors or induce
spikes on neighbouring circuits. It’s common use is to amalgamate all the alarm signals
into one, volts-free relay contact pair for the main alarm system.
Note that the board is available for different voltages (12 or 24V) depending on the type
of relay fitted at RL1.

5.1.9 24V 400W Flat-Pack Power Supply (96-300011)
5.1.9.1
Description
The power supply unit is a switched-mode type capable of supplying 24V DC at 16.0Amps
continuously. Equipment of this type typically requires approximately 10.0 Amps at 24V
DC, so the PSU will be used conservatively ensuring a long operational lifetime.
No routine maintenance of the PSU is required. If a fault is suspected, then the output
voltage from the power supply may be measured on its output terminals. This is typically
set to 24.5V.
All the PSU’s used in AFL Cell Enhancers are capable of operation from either 110 or
220V nominal AC supplies. The line voltage is sensed automatically, so no adjustment or
link setting is needed by the operator. No drawings of the PSU are available.

5.1.11.1
Description
The F/O units consist of a receiver & transmitter, which modulates the RF signal onto a laser
carrier and transmits it via fibre/optic cable to a receiver unit some distance away where it is
demodulated back to the original RF signal with very small values of accrued attenuation.
Both transmitter and receiver modules have their own dedicated alarm outputs (volt-free relay
contacts) which are integrated into the main alarm system. Being O.E.M devices, no drawings
or circuit diagrams are available.
Caution: The FO units are NOT weather proof.

5.2.1.1
Description
Fitted in Unit 2 after the amplification stages is a 2 element notch filter (one in downlink,
one in uplink), which is designed to reject the uplink frequencies in the downlink path and
vice-versa. The notch filter is not required for Unit One as the rejection from the two
series bandpass filters as apposed to one, is sufficient to meet the specification.

5.2.2 Crossband Couplers (07-004801 & 07-005705)
5.2.2.1
Description
The purpose of a crossband coupler is to either combine/split transmission signals from
different parts of the frequency spectrum.
The crossband coupler fitted here, is the means by which the separate UHF & GSM frequency
band signals are mixed to form a composite RF signal.
It basically comprises of a 3 port device, two filters, one a low pass the other a high pass, that
are then mixed and fed to a common output. The couplers are built into a machined aluminium
casing having a centre screening wall between the filter sections and lid secured by screws at
frequent intervals over its perimeter to obtain a tight seal and to ensure linearity and stability
of response.

800MHz Bi-Directional Air Interface Amplifier (60-056103)
5.3.1 Bandpass Filter (02-007201)
5.3.1.1
Description
The bandpass filters are multi-section designs with a bandwidth dependent upon the passband
frequencies, (both tuned to customer requirements). The response shape is basically
Chebyshev with a passband design ripple of 0.1dB. The filters are of slot coupled, folded
combline design, and are carefully aligned during manufacture in order to optimise the
insertion loss, VSWR and intermodulation characteristics of the unit. The tuned elements are
silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50? load
at the input and output ports.
Being passive devices, the bandpass filters should have an extremely long operational life and
require no maintenance. Should a filter be suspect, it is usually most time efficient to replace
the module rather than attempt repair or re-tuning.
No adjustments should be attempted without full network sweep analysis facilities to monitor
both insertion loss and VSWR simultaneously.

Description
The Gallium-Arsenide low noise amplifier used in the unit is a double stage, solid-state low
noise amplifier. Class A circuitry is used throughout the units to ensure excellent linearity and
extremely low noise over a very wide dynamic range. The active devices are very moderately
rated to provide a long trouble-free working life. There are no adjustments on these
amplifiers, and in the unlikely event of a failure, then the complete amplifier should be
replaced. This amplifier features its own in-built alarm system which gives a volt-free relay
contact type alarm that is easily integrated into the main alarm system.

5.3.4 5Watt Power Amplifier (12-000201)
5.3.4.1
Description
The power amplifier fitted to this unit is a multi-stage, solid state power amplifier. Class A
circuitry is employed throughout the device to ensure excellent linearity over a wide
dynamic frequency range. All the semi-conductor devices are very conservatively rated to
ensure low device junction temperatures and a long, trouble free working lifetime.
The power amplifier should require no maintenance over its operating life. Under no
circumstances should the cover be removed or the side adjustments disturbed unless it is
certain that the amplifier has failed; since it is critically aligned during manufacture and any
re-alignment will require extensive test equipment.

5.3.7 Channel Control & Channel Selective Modules (17-002101 & 17-003002)
5.3.7.1
Channel Selective Module Description
The channel selectivity module is employed when the Cell Enhancer requirement dictates that
very narrow bandwidths (single operating channels), must be selected from within the
operating passband. One channel selectivity module is required for each channel.
The Channel Selectivity Module is an Up/Down frequency converter that mixes the incoming
channel frequency with a synthesised local oscillator, so that it is down-converted to an
Intermediate Frequency (IF) in the upper HF range. An eight pole crystal filter in the IF
amplifier provides the required selectivity to define the operating passband of the Cell
Enhancer to a single PMR channel. The same local oscillator then converts the selected IF
signal back to the channel frequency.
Selectivity is obtained from a fixed bandwidth block filter operating at an intermediate
frequency (IF) in the low VHF range. This filter may be internal to the channel selectivity
module (Crystal or SAW filter) or an externally mounted bandpass filter, (LC or Helical
Resonator). Various IF bandwidths can therefore be accommodated. A synthesized Local
Oscillator is employed in conjunction with high performance frequency mixers, to translate
between the signal frequency and IF.
The operating frequency of each channel selectivity module is set by the programming of
channel selectivity module frequencies and is achieved digitally, via hard wired links, banks of
DIP switches, or via an onboard RS232 control module, providing the ability to remotely set
channel frequencies.
Automatic Level Control (ALC) is provided within each channel selectivity module such that
the output level is held constant for high level input signals. This feature prevents saturation of
the output mixer and of the associated amplifiers.
Alarms within the module inhibit the channel if the synthesised frequency is not locked. The
synthesiser will not usually go out of lock unless a frequency far out of band is programmed.
The channel selectivity module is extremely complex and, with the exception of channel
frequency programming within the design bandwidth, it cannot be adjusted or repaired without
extensive laboratory facilities and the necessary specialised personnel. If a fault is suspected
with any channel selectivity module it should be tested by substitution and the complete,
suspect module should then be returned to AFL for investigation.

INSTALLATION
6.1
Initial Installation Record
When this equipment is initially commissioned, please use the equipment set-up record sheet
in Appendix A. This will help both the installation personnel and AFL should these figures be
needed for future reference or diagnosis.
6.2
General
The size and weight of the wall units mean that they represent a significant health hazard
unless they are mechanically installed in the correct manner. In the interests of safety this
should be done before any electrical, RF, or optical connections are made.
It is important in determining the location of the wall units that space is allowed for access to
the front and underneath of the equipment. To enable maintenance to be carried out, the door
must be able to fully open. The location must be served with a duct to allow the entry of
cables into the unit.
6.3
Electrical Connections
The mains power supply and the alarms are connected through an IP65 connector which
should need no further attention once connected. It is recommended that the AC power
connection is approved by a qualified electrician, who must satisfy himself that the supply will
be the correct voltage and of sufficient capacity.
All electrical and RF connection should be completed and checked prior to power being
applied for the first time.
6.4
Optical Connections
The optical input and output ports are be located on a bracket fixed to the lower inside of the
case. The optical fibres from the tunnels enter through a cable gland on the case underside
The ports are supplied with a green plastic cover, which must be removed prior to the
connection of the fibre cable. Ensure that transmitter and receiver fibre cable are identified to
prevent misconnection. At the master site, the fibre transmitters are in the downlink path with
the receivers in the uplink. At the remote sites the fibre transmitters are in the uplink with the
receivers in the downlink. Where some of the fibre optic transmitter outputs are split with
optical couplers to provide a connection to more than one remote site, care must be taken to
ensure that the correct connections are made.
Ensure that connections are kept clean and are fully tightened.

6.5
RF Connections
All RF connections are made to the cable termination, located on the right-hand side of the
wall enclosure. Care must be taken to ensure that the correct connections are made with
particular attention made to the base station TX/RX ports. In the event that the base
transmitter is connected to the RX output of the rack, damage to the equipment may be done
if the base station transmitter is then keyed. If the environment where the equipment is
installed is deemed to be ‘wet’ i.e. water seepage through roofs or walls, then suitable
methods to seal the RF N type connectors should be used, for example self amalgamating
sealant tape.
Ensure that connections are kept clean and are fully tightened.
6.6
Commissioning
Once all connections are made the equipment is ready for commissioning.
To commission the system the test equipment detailed in section 7.2 will be required.
Using the system diagrams and the end-to-end test specification, the equipment should be
tested to ensure correct operation. Typical RF levels that are not listed in the end-to-end
specification, such as input levels to the fibre transmitters are detailed in the whole system
diagram in section 4.
On initial power up the system alarm indicators on the door of the equipment should be
checked. A red LED illuminated indicates a fault and that particular module must be
investigated before proceeding with the commissioning. A green LED illuminates, to indicate
that the power supply is connected and valid.
The individual fibre optic units are fitted with a pair of status indicators on their front panels.
One is a green LED, which indicates that the unit is connected to a 15 Volt power supply.
This indicator is common to both transmit and receive units. The second LED on the
transmitter indicates that the laser is operating. On the receive unit the second LED indicates
that a light signal is being received.
When all the fibre connections are completed and power to each site is connected each fibre
unit should show two illuminated indicators.
In the event that any part of the system does not function correctly as expected, check all
connections to ensure that they are to the correct port, that the interconnecting cables are not
faulty and that they are tightened. The majority of commissioning difficulties arise from
problems with the interconnecting cables and connectors.

MAINTENANCE
7.1
General Procedures
7.1.1 Fault Finding
In the event that the performance of the system is suspect, a methodical and logical approach
to the problem will reveal the cause of the difficulty. The System consists of modules within a
wall mounted, environmentally protected enclosure.
Transmissions from the main base stations are passed though the system to the mobile radio
equipment; this could be a handheld walkie-talkie, mobile telephone or a transceiver in a
vehicle. This path is referred to as the downlink. The return signal path from the mobile radio
equipment to the base station is referred to as the uplink.
The first operation is to check the (optional) alarms of each of the active units and determine
that the power supplies to the equipment are connected and active.
This can be achieved remotely (via CEMS, the digital RS232 Cell Enhancer Management
System, if fitted), or locally with the front door LED’s. The green LED on the front door
should be illuminated, while the red alarm indicator should be off.
If an Alarm is on, then that individual module must be removed and tested against the original
test specification.
The individual amplifier units have a green LED showing through a hole in their piggy-back
alarm board (or directly through a hole in the the amplifier lid), which is illuminated if the unit
is working correctly.
If an amplifier is suspect, check the DC power supply to the unit. If no other fault is apparent
use a spectrum analyser to measure the incoming signal level at the input and then after
reconnecting the amplifier input, measure the output level. Consult with the system diagram
and amplifier specification to determine the expected gain and compare result.
In the event that there are no alarms on and all units appear to be functioning it will be
necessary to test the system in a logical manner to confirm correct operation.

7.1.2 Downlink
Confirm that there is a signal at the expected frequency and strength from the base station. If
this is not present then the fault may lay outside the system. To confirm this, inject a
downlink frequency signal from a known source at the master site BTS input and check for
output at the remote site feeder output.
If a signal is not received at the output it will be necessary to follow the downlink path
through the system to find a point at which the signal is lost. The expected downlink output
for the given input can be found in the end-to-end test specification.
7.1.3 Uplink
Testing the uplink involves a similar procedure to the downlink except that the frequencies
used are those transmitted by the mobile equipment.
7.1.4 Fault repair
Once a faulty component has been identified, a decision must be made on the appropriate
course to carry out a repair. A competent engineer can quickly remedy typical faults such as
faulty connections or cables. The exceptions to this are cable assemblies connecting bandpass
filter assemblies that are manufactured to critical lengths to maintain a 50-ohm system. Care
should be taken when replacing cables or connectors to ensure that items are of the correct
specification. The repair of component modules such as amplifiers, tuned cavities or bandpass
filters will not usually be possible in the field, as they frequently require specialist knowledge
and test equipment to ensure correct operation. It is recommended that items of this type are
replaced with a spare unit and the faulty unit returned to AFL for repair. If spare parts need
to be ordered from AFL, be sure to quote the serial number of the Cell Enhancer/Repeater
and the serial number [and frequencies] of the module(s) to be replaced.

7.1.5 Checking service
Following the repair of any part of the system it is recommended that a full end-to-end test is
carried out in accordance with the test specification and that the coverage is checked by
survey.
It is important to bear in mind that the system includes a radiating cable network and base
stations that may be faulty or may have been damaged.

7.3
Care of Modules
7.3.1 General Comments
Many of the active modules contain semiconductor devices utilising MOS technology, which
can be damaged by electrostatic discharge. Correct handling of such modules is mandatory to
ensure their long-term reliability.
To prevent damage to a module, it must be withdrawn/inserted with care. The module may
have connectors on its underside, which might not be visible to the service operative.
7.3.2 Module Removal (LNA’s, general procedure):
The following general rules should be followed to remove a module:
Remove power to the unit
Remove all visible connectors (RF, DC & alarm)
Release module retaining screws.
Slowly but firmly, pull the module straight out of its position. Take care not to twist/turn
the module during withdrawal. (When the module is loose, care may be needed, as there
may be concealed connections underneath).
7.3.3 Module Replacement (general):
Carefully align the module into its location then slowly push the module directly straight
into its position, taking care not to twist/turn it during insertion.
Reconnect all connectors, RF, alarm, power etc.,(concealed connectors may have to be
connected first).
Replace retaining screws (if any).
Double-check all connections before applying power.
7.3.4 Power Amplifiers
1) Remove power to the unit. (Switch off @ mains/battery, or remove DC in connector)
2) Remove alarm wires from alarm screw terminal block or disconnect multi-way alarm
connector.
3) Carefully disconnect the RF input and output coaxial connectors (usually SMA)
If alarm board removal is not required, go to step 5.
4) There is (usually) a plate attached to the alarm board which fixes it to the amplifier,
remove its retaining screws and the alarm board can be withdrawn from the amplifier in its
entirety. On certain types of amplifier the alarm board is not mounted on a dedicated
mounting plate; in this case it will have to firstly be removed by unscrewing it from the
mounting pillars, in most cases, the pillars will not have not have to be removed before
lifting the amplifier.

5) If the amplifier to be removed has a heatsink attached, there may be several different ways
it can have been assembled. The most commonly used method, is screws through the front
of the heatsink to threaded screw holes (or nuts and bolts), into the amplifier within the
main case. If the heatsink is mounted on the rear of the main case (e.g., against a wall in
the case of wall mounted enclosures), then the fixing method for the heatsink will be from
within the case, (otherwise the enclosure would have to be removed from the wall in order
to remove the heatsink).
When the heatsink has been removed, the amplifier may be unscrewed from the main
casing by its four corner fixings and gently withdrawn.
Fitting a new power amplifier module will be the exact reverse of the above.
Note: Do not forget to apply fresh heatsink compound to the heatsink/main case
joint and also between the amplifier and the main case.
7.3.5 Low Power Amplifier Replacement
Disconnect the mains power supply and disconnect the 24V dc supply connector for the
LPA.
Disconnect the RF input and output cables from the LPA.
Disconnect the alarm connector.
Remove the alarm monitoring wires from (D type connector) pins 9 and 10.
Remove the LPA module by removing the four retaining screws, replace with a new LPA
module and secure it with the screws.
Connect the RF cables to the LPA input and output connectors. Reconnect the wires to
the alarm board connector pins 9 and 10.
Reconnect the DC supply connector and turn the mains switch on.
Note:
Tighten SMA connectors using only a dedicated SMA torque spanner. If
SMA connectors are over-tightened, irreparable damage will occur. . Do not use
adjustable pliers to loosen/tighten SMA connectors.
Also take care not to drop or knock the module as this can damage (or misalign in the
case of tuned passive modules) sensitive internal components. Always store the modules
in an environmentally friendly location
7.3.6 Module Transportation:
To maintain the operation, performance and reliability of any module it must be stored and
transported correctly. Any module not installed in a whole system must be kept in an antistatic bag or container. These bags or containers are normally identified by being pink or
black, and are often marked with an ESD label. Any module sent back to AFL for
investigation/repair must be so protected. Please contact AFL’s quality department before
returning a module.

If the input signal level in the uplink path is known and steady, use the following calculation
table to determine the gain setting. If the CE features Automatic Gain Control the attenuator
should be set to zero and if not, then the attenuation setting for both uplink and downlink
should be similar.
