SAFETY CONSIDERATIONS
1.1
Earthing of Equipment
Cell Enhancers supplied from the mains must be connected to grounded outlets and earthed
in conformity with appropriate local, national and international electricity supply and safety
regulations.
1.2
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.

1.3
RF Radiation Hazard
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 50Ω, and that of free space at 377Ω, 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.

1.4
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.

Laser safety
General good working practices adapted from EN60825-2: 1994
“Do not stare with unprotected eyes or with any unapproved optical device at the fibre ends or
connector faces or point them at other people.”
“Use only approved filtered or attenuating viewing aids.”
“Any single or multiple fibre end or ends found not to be terminated (for example, matched,
spliced) shall be individually or collectively covered when not being worked on. They shall
not be readily visible and sharp ends shall not be exposed.”
“When using test cords, the optical power source shall be the last connected and the first
disconnected.”
“Use only approved methods for cleaning and preparing optical fibres and optical
connectors.”
Always keep optical connectors covered to avoid physical damage
Do not allow any dirt/foreign material ingress on the optical connector bulkheads.
The optical fibre jumper cable maximum bend radius is 3cm, any smaller radii may result in
optical cable breakage or excessive transmission losses.
Caution: Do not get them wet, the FO units are NOT weather proof.

SYSTEM OVERVIEW
The equipment is manufactured in standard IP54 19” rack shelves and is powered by the
local mains supply. No battery backup is fitted.
The remote site receives the master site RF data via a dedicated fibre link. The downlink fibre
signals are transmitted to the remote site using 1310nm wavelength laser and the uplink
wavelength from remote to master site is 1550nm, using wave division multiplexing to
differentiate between the wavelengths. This means that a single fibre cable can be used for
both uplink and downlink, saving the considerable cost of an extra fibre cable between master
and each remote site.
The 10Watt output power remote BDA drives an air interfaced antenna for the local mobile
coverage.

3.1.1
Remote Site 10W BDA Description
The remote site 10W Bi-Directional Amplifier receives downlink signals from the Fibre
Optic shelf at port A and passes them through a bandpass filter tuned to the downlink
passband (408-411MHz). From there the signal is amplified by a Low Noise Amplifier
(+31dB) and a 0-15dB switched attenuator to a 10Watt power amplifier (22dB). A final
bandpass filter completes the downlink path to the off-air antenna (port C).
The uplink path starts at the off-air antenna (port C)and is passed first through a bandpass
filter tuned to the uplink band (417-420MHz). A 20dB amplifier and switched attenuator
amplify the signal by 20dB and the signal then passes through a final bandpass filter to the
AGC attenuator. After the attenuator the signal is amplified to one Watt power to the AGC
logarithmic detector giving this path a dynamic range of approximately 30dB. After the
AGC detector the signal exits the shelf to the FO shelf at port B.

Bandpass Filters (02-007302)
4.1.1
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 50Ω 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.

Switched Attenuator (10-000901)
4.2.1
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. The attenuators are located between the first and second stage
amplifiers, (fitting the attenuators in any other position would be detrimental to the noise
and/or output power performance of the Cell Enhancer).
4.2.2 Switched Attenuators
The AFL switched attenuators are available in two different types; 0 – 30dB in 2 dB steps, or
0 – 15dB in 1 dB steps (as in this case). The attenuation is simply set using the four miniature
toggle switches on the top/side 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 50Ω impedance over their operating frequency at
both input and output and have a low ‘0dB’ insertion loss, typically less than 0.3dB.

Low Noise Amplifiers (11-007302 & 11-007402)
4.3.1
Description
The low noise amplifier used is a double stage solid-state low-noise amplifier. Class A
circuitry is used in the unit to ensure excellent linearity over a very wide dynamic range. The
two active devices are very moderately rated to provide a long trouble-free working life.
There are no adjustments on this amplifier, and in the unlikely event of failure then the entire
amplifier should be replaced. Note that the two amplifiers use similar DC/bias circuits.

4.6.1
Wide Dynamic Range AGC (17-001105, Det. & 17-001201, Atten.)
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 50Ω 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, (factory set @ time of system test) do not adjust unless able to monitor
subsequent RF levels.
The attenuator comprises a 50Ω 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.

24V Single Relay Board (80-008901)
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.

JWS150-24/A PSU (96-300060)
Description
The power supply unit is a switched-mode type capable of supplying 24V DC at
6.25Amps continuously. Equipment of this type typically requires approximately 22.5Amps 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. The output voltage may be varied using a multi-turn adjustment
potentiometer mounted close to the DC output terminals.
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.

INSTALLATION

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.
5.2
Installation & Attenuator Settings
The UHF Fibre Optic System comprises a remote site fibre driven 10Watt bi-direction
amplifier. It is fed from a fibre optic tray which links to the master site fibre optic tray via a
single fibre optic cable. The Tx and Rx signals use different optical frequencies and are
coupled using wave division multiplexers (WDMs). The three BDA will feed either an omnidirectional antenna or leaky feeders to provide UHF radio coverage in areas where signal
levels and reception from the BTS are poor and in which the mobiles are to be served.
The duplexer, fibre optic and BDA trays are all designed to be mounted in standard 19”
equipment racks.
The maximum output from the BDAs is limited by built-in AGC circuits. The gain in both the
downlink and the uplink paths can be adjusted using switched attenuators which can be
accessed from the rear panels of the BDA trays. The master site is also fitted with attenuators
which control the signal levels to and from the master site fibre optic tray. All switched
attenuators are switched to maximum attenuation prior to despatch.
The downlink attenuator in the master site should be adjusted so that -14dBm is available
from the downlink connector when one channel is being driven at maximum power by the
BTS. The uplink attenuator in the master site should be adjusted so that an input signal to the
uplink connector of -5dBm will provide a maximum signal to the coupler of -20dBm.
The downlink attenuator on the 10W BDA should be adjusted so that an input signal of
-10dBm provides an output to the antenna connector of +25dBm. The uplink attenuator on the
10W BDA should be adjusted so that an input signal of -50dBm will provide an output of
0dBm to the Uplink F/O Tray connector.
