SAFETY CONSIDERATIONS1.1 Electric Shock HazardElectrical shocks due to faulty mains driven power supplies.Whilst ever potentially present in any electrical equipment, such a condition would beminimised 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 suppliescan be dangerous because of the possibility of substantial arcing. Always switch off duringdisconnection and reconnection.1.2 RF Radiation Hazard“CAUTION: This equipment is approved for antennas mounted on fixed outdoor permanentstructures. A minimum separation distance of 2 metres must be maintained between theradiating 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 levelsabove the limits allowed by FCC rules.”This equipment complies with part 90 of the FCC rules. Any changes or modifications notexpressly approved by the manufacturer could void the user’s authority to operate theequipment.RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected toAFL’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’sefficiency. No investigation should be carried out until all RF power sources have beenremoved. This would always be a wise precaution, despite the severe mismatch between theimpedance of an N type connector at 50Ω, and that of free space at 377Ω, which wouldseverely mitigate against the efficient radiation of RF power. Radio frequency burns couldalso 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 iscapable of producing RF field strengths, which may exceed guideline safe values especially ifused with antennas having appreciable gain. In this regard the use of directional antennaswith backscreens and a strict site rule that personnel must remain behind the screen while theRF power is on, is strongly recommended.Where the equipment is used near power lines, or in association with temporary masts nothaving lightning protection, the use of a safety earth connected to the case-earthing bolt isstrongly advised.
800MHz BDA (Pasadena Figuero Tunnel)Maintenance HandbookH/book Number:-60-056100HBKM Issue No:-1 Date:-21/10/2003 Page:-9 of 521.3 Chemical HazardBeryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes usedin devices within equipment produced by Aerial Facilities Ltd. Beryllium oxide dust can betoxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or bycontact.Products that contain beryllium are load terminations (dummy loads) and some poweramplifiers. 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 internationalregulations, but pose no threat under normal circumstances. Only if a component containingberyllium oxide has suffered catastrophic failure, or exploded, will there be any danger of theformation of dust. Any dust that has been created will be contained within the equipmentmodule as long as the module remains sealed. For this reason, any module carrying theyellow 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 aReturned Materials Authorisation (RMA) number. Please quote this number on the packingdocuments, and on all correspondence relating to the shipment.PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite MaterialsMany modules/components in AFL equipment contain P.T.F.E. as part of the RF insulationbarrier.This material should never be heated to the point where smoke or fumes are evolved. Anyperson feeling drowsy after coming into contact with P.T.F.E. especially dust or fumesshould seek medical attention.1.4 Emergency Contact NumbersThe AFL Quality Department can be contacted on:Telephone +44 (0)1494 777000Fax +44 (0)1494 777002e-mail qa@aerial.co.uk

OVERVIEW/SYSTEM DESCRIPTIONThe AFL 800MHz Off Air Amplifier for the Pasadena Blue line project is an 8 waychannelised RF amplifier. It’s application is as an air interface between the donor radio siteand the tunnel leaky feeder system. The unit is housed in an environmentally protected IP65steel wall-mount case. Handles are provided for carrying the unit and the door is fitted withlocks. The unit interfaces with ‘N’ type female connectors for RF connections and heavy dutyconnectors for routing of AC power supply input and alarm output wiring.The unit is housed in an environmentally protected IP65 steel wall-mount case. Handles areprovided 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 ACpower supply input and alarm output wiring.To provide adequate selectivity in the Downlink and Uplink paths, combline designduplexers are used at the input and output ports. To provide the required gain to reach therequired signal levels, low-noise amplifiers (LNA’s) are used in each path, these beingfollowed by power amplifier modules 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.

SUB-UNIT MODULES5.1 Bandpass Filter (02-011601)5.1.1 DescriptionThe bandpass filters are multi-section designs with a bandwidth dependent upon thepassband frequencies, (both tuned to customer requirements). The response shape isbasically Chebyshev with a passband design ripple of 0.1dB. The filters are of comblinedesign, 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-platedto reduce surface ohmic losses and maintain a good VSWR figure and 50Ω load at the inputand output ports.Being passive devices, the bandpass filters should have an extremely long operational lifeand require no maintenance. Should a filter be suspect, it is usually most time efficient toreplace the module rather than attempt repair or re-tuning.5.1.2 Technical SpecificationPARAMETER SPECIFICATIONResponse Type: Chebyshev857-861MHz (Dlink)Frequency Range: 812-816MHz (Ulink)Bandwidth: <7.5 MHz (tuned to requirements)Number of Sections: 8Insertion Loss: 1.2 dBVSWR: better than 1.2:1Connectors: SMAPower Handling: 100W maxoperation: -10°C to +55°CTemperature range storage: -40°C to +70°CWeight: 3 kg (typical)

Any unused ports will be terminated with an appropriate 50Ω load.5.2.2 Technical SpecificationPARAMETER SPECIFICATIONNarrowband: 800-1000MHzFrequency Range: Broadband: 600-1300MHzNarrowband: 300 MHzBandwidth: Broadband: 700 MHzInputs: 1Outputs: 2Narrowband: >20 dBIsolation: Broadband: >18 dBNarrowband: 3.3 dBInsertion Loss: Broadband: 3.5 dBVSWR Input & Output: Better than 1.3:1Impedance: 50 ςConnectors: SMA femaleWeight: 200gmsSize: 54 x 44 x 21mm (includingconnectors)Splitter: 20 WattsPower Rating: Combiner: 0.5Watts

Any unused portswill be terminated with an appropriate 50Ω load. This splitter is used in conjunction withthe previously mentioned 05-002602 to split & combine the signal before and after thechannel selective modules (in both up & downlink paths).5.3.2 Technical SpecificationPARAMETER SPECIFICATIONFrequency range: 700-1000MHzBandwidth: >200MHzRejection: >14dBInsertion loss: 6.5dB (typical)Connectors: SMAWeight: <1.5kgoperational:-10ΒC to +55ΒCTemperaturerange: storage -40ΒC to +70ΒC5.4 ¼Watt 0- -30dB Switched Attenuator (10-000701)5.4.1 General ApplicationIn many practical applications for Cell Enhancers etc., the gain in each path is found to beexcessive. Therefore, provision is made within the unit for the setting of attenuation ineach path, to reduce the gain.5.4.2 Switched AttenuatorsThe 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 fourminiature toggle switches on the top of each unit. Each switch is clearly marked with theattenuation it provides, and the total attenuation in line is the sum of the values switchedin. They are designed to maintain an accurate 50Ω impedance over their operatingfrequency at both input and output.

Class A circuitry is used throughout the units to ensure excellent linearityand extremely low noise over a very wide dynamic range. The active devices are verymoderately rated to provide a long trouble-free working life. There are no adjustments onthese amplifiers, and in the unlikely event of a failure, then the complete amplifier should bereplaced. This amplifier features its own in-built alarm system which gives a volt-free relaycontact type alarm that is easily integrated into the main alarm system.5.5.2 Technical Specification (11-005902)PARAMETER SPECIFICATIONFrequency Range: 800 – 960MHzBandwidth: <170MHzGain: 19.5dB (typical)1dB Compression Point: 21dBmOIP3: 33dBmInput/Output Return Loss: >20dBNoise Figure: 1dB (typical)Power Consumption: 190mA @ 24V DCSupply Voltage: 10-24V DCConnectors: SMA femaleoperational: -10°C to +55°CTemperature Range: storage: -40°C to +70°CSize: 90 x 55 x 30.2mmWeight: 280gms (approximately)

Any departure from normal biasconditions 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 voltageof 1.20V across the collector current setting resistor. The Amplifier Alarm Board is awindow comparator device, which is adjusted to sense a departure from this condition.Several different alarm outputs are provided to simplify interfacing, (Relay Contact, OpenCollector, and TTL Logic Levels)The basic version of the Alarm Board (12-002801) monitors a single amplifier stage. Athree-stage version (12-002201) is used on complex amplifiers where three separatecomparators have their outputs logically combined to a common output stage. Failure ofany one stage will activate the alarms.Note that the alarm board has a green Light Emitting Diode located near to the centre ofthe printed circuit board, which is illuminated on ‘Good’, and extinguished on ‘Alarm’. Itis therefore a simple matter to identify an active module failure, by searching for anAlarm Board which has its green LED extinguished. A simple test of the alarm board ispossible by shorting across the monitor inputs, pins 1 and 2, 3 and 4 or across pins 5 and6. This last monitor input is inactive if the board has been converted to a two way alarmboard. (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 initialadjustment or calibration, and the board will function correctly with a wide variation inpower supply voltage (8 to 30 volts, nominal supply is 12 or 24Volts).There are two selectable link options on the three-way board:LINK1 - Removed to convert to two-way alarm board.LINK2 - Removed to isolate 0V from chassis earth.The one way alarm board only has the 0V isolation link (LINK2) fitted.

One channel selectivity module is required for each channel.The Channel Selectivity Module is an Up/Down frequency converter that mixes the incomingchannel frequency with a synthesised local oscillator, so that it is down-converted to anIntermediate Frequency (IF) in the upper HF range. An eight pole crystal filter in the IFamplifier provides the required selectivity to define the operating passband of the CellEnhancer to a single PMR channel. The same local oscillator then converts the selected IFsignal back to the channel frequency.Selectivity is obtained from a fixed bandwidth block filter operating at an intermediatefrequency (IF) in the low VHF range. This filter may be internal to the channel selectivitymodule (Crystal or SAW filter) or an externally mounted bandpass filter, (LC or HelicalResonator). Various IF bandwidths can therefore be accommodated. A synthesized LocalOscillator is employed in conjunction with high performance frequency mixers, to translatebetween the signal frequency and IF.The operating frequency of each channel selectivity module is set by the programming ofchannel selectivity module frequencies and is achieved digitally, via hard wired links, banksof DIP switches, or via an onboard RS232 control module, providing the ability to remotelyset channel frequencies.Automatic Level Control (ALC) is provided within each channel selectivity module such thatthe output level is held constant for high level input signals. This feature prevents saturationof the output mixer and of the associated amplifiers.Alarms within the module inhibit the channel if the synthesised frequency is not locked. Thesynthesiser 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 channelfrequency programming within the design bandwidth, it cannot be adjusted or repairedwithout extensive laboratory facilities and the necessary specialised personnel. If a fault issuspected with any channel selectivity module it should be tested by substitution and thecomplete, suspect module should then be returned to AFL for investigation.

Equipment of this type typically requires approximately 10.0 Amps at 24VDC, 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 outputvoltage from the power supply may be measured on its output terminals. This is typically setto 24.5V.All the PSU’s used in AFL Cell Enhancers are capable of operation from either 110 or 220Vnominal AC supplies. The line voltage is sensed automatically, so no adjustment or linksetting is needed by the operator. No drawings of the PSU are available.5.11.2 Technical SpecificationAC Input Supply:Voltage: 110 or 220V nominal - 90 to 132 or 180 to264V (single phase, absolute limits)Frequency: 47 to 63HzDC Output Supply:Voltage: 24V DC (nominal), 22 to 26V(absolute limits)Current: 16.0Aoperational: -10ΒC to +55ΒCTemperaturerange: storage: -40ΒC to +70ΒC

INSTALLATION6.1 Initial Installation RecordWhen this equipment is initially commissioned, please use the equipment set-up record sheetin Appendix A. This will help both the installation personnel and AFL should these figuresbe needed for future reference or diagnosis.6.2 GeneralThe size and weight of the wall unit means that it represent a significant health hazard unlessit is mechanically installed in the correct manner. In the interests of safety this should bedone before any electrical or RF connections are made.It is important in determining the location of the wall units that space is allowed for accessto the front and underneath of the equipment. To enable maintenance to be carried out, thedoor must be able to fully open. The location must be served with a duct to allow the entryof cables into the unit.6.3 Electrical ConnectionsThe mains power supply and the alarms are connected through an IP65 connector whichshould need no further attention once connected. It is recommended that the AC powerconnection is approved by a qualified electrician, who must satisfy himself that the supplywill be the correct voltage and of sufficient capacity.All electrical and RF connection should be completed and checked prior to power beingapplied for the first time.6.4 RF ConnectionsAll RF connections are made to the cable termination, located on the right-hand side of thewall enclosure. Care must be taken to ensure that the correct connections are made withparticular attention made to the base station TX/RX ports. In the event that the basetransmitter is connected to the RX output of the unit, damage to the equipment may be doneif the base station transmitter is then keyed. If the environment where the equipment isinstalled is deemed to be ‘wet’ i.e. water seepage through roofs or walls, then suitablemethods to seal the RF N type connectors should be used, for example self amalgamatingsealant tape.Ensure that connections are kept clean and are fully tightened.
800MHz BDA (Pasadena Figuero Tunnel)Maintenance HandbookH/book Number:-60-056100HBKM Issue No:-1 Date:-21/10/2003 Page:-46 of 526.5 CommissioningOnce 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 betested to ensure correct operation. Typical RF levels that are not listed in the end-to-endspecification, such as input levels 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 bechecked. A red LED illuminated indicates a fault and that particular module must beinvestigated before proceeding with the commissioning. A green LED illuminates, toindicate that the power supply is connected and valid.In the event that any part of the system does not function correctly as expected, check allconnections to ensure that they are to the correct port, that the interconnecting cables are notfaulty and that they are tightened. The majority of commissioning difficulties arise fromproblems with the interconnecting cables and connectors.

MAINTENANCE7.1 General Procedures7.1.1 Fault FindingIn the event that the performance of the system is suspect, a methodical and logical approachto the problem will reveal the cause of the difficulty. The System consists of modules withina wall mounted, environmentally protected enclosure.Transmissions from the main base stations are passed though the system to the mobile radioequipment; this could be a handheld walkie-talkie, mobile telephone or a transceiver in avehicle. This path is referred to as the downlink. The return signal path from the mobileradio 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 determinethat the power supplies to the equipment are connected and active.This can be achieved remotely (via CEMS, the digital RS232 Coverage EnhancementManagement System, if fitted), or locally with the front door LED’s. The green LED on thefront 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 theoriginal test specification.The individual amplifier units have a green LED showing through a hole in their piggy-backalarm board (or directly through a hole in the amplifier lid), which is illuminated if the unitis working correctly.If an amplifier is suspect, check the DC power supply to the unit. If no other fault isapparent use a spectrum analyser to measure the incoming signal level at the input and thenafter reconnecting the amplifier input, measure the output level. Consult with the systemdiagram 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 benecessary to test the system in a logical manner to confirm correct operation.
800MHz BDA (Pasadena Figuero Tunnel)Maintenance HandbookH/book Number:-60-056100HBKM Issue No:-1 Date:-21/10/2003 Page:-48 of 527.1.2 DownlinkConfirm that there is a signal at the expected frequency and strength from the base station. Ifthis is not present then the fault may lay outside the system. To confirm this, inject adownlink frequency signal from a known source at the master site BTS input and check foroutput at the remote site feeder output.If a signal is not received at the output it will be necessary to follow the downlink paththrough the system to find a point at which the signal is lost. The expected downlink outputfor the given input can be found in the end-to-end test specification.7.1.3 UplinkTesting the uplink involves a similar procedure to the downlink except that the frequenciesused are those transmitted by the mobile equipment.7.1.4 Fault repairOnce a faulty component has been identified, a decision must be made on the appropriatecourse to carry out a repair. A competent engineer can quickly remedy typical faults such asfaulty connections or cables. The exceptions to this are cable assemblies connectingbandpass filter assemblies that are manufactured to critical lengths to maintain a 50-ohmsystem. Care should be taken when replacing cables or connectors to ensure that items are ofthe correct specification. The repair of component modules such as amplifiers, tuned cavitiesor bandpass filters will not usually be possible in the field, as they frequently requirespecialist knowledge and test equipment to ensure correct operation. It is recommended thatitems of this type are replaced with a spare unit and the faulty unit returned to AFL forrepair. If spare parts need to be ordered from AFL, be sure to quote the serial number of theCell Enhancer/Repeater and the serial number [and frequencies] of the module(s) to bereplaced.

Correct handling of such modules is mandatory toensure their long-term reliability.To prevent damage to a module, it must be withdrawn/inserted with care. The module mayhave 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:1 Remove power to the unit2 Remove all visible connectors (RF, DC & alarm)3 Release module retaining screws.4 Slowly but firmly, pull the module straight out of its position. Take care not to twist/turnthe module during withdrawal. (When the module is loose, care may be needed, as theremay be concealed connections underneath).7.3.3 Module Replacement (general):1 Carefully align the module into its location then slowly push the module directly straightinto its position, taking care not to twist/turn it during insertion.2 Reconnect all connectors, RF, alarm, power etc.,(concealed connectors may have to beconnected first).3 Replace retaining screws (if any).4 Double-check all connections before applying power.7.3.4 Power Amplifiers1) 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 alarmconnector.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 inits entirety. On certain types of amplifier the alarm board is not mounted on a dedicatedmounting plate; in this case it will have to firstly be removed by unscrewing it from themounting pillars, in most cases, the pillars will not have not have to be removed beforelifting the amplifier.
800MHz BDA (Pasadena Figuero Tunnel)Maintenance HandbookH/book Number:-60-056100HBKM Issue No:-1 Date:-21/10/2003 Page:-51 of 525) If the amplifier to be removed has a heatsink attached, there may be several differentways it can have been assembled. The most commonly used method, is screws throughthe front of the heatsink to threaded screw holes (or nuts and bolts), into the amplifierwithin the main case. If the heatsink is mounted on the rear of the main case (e.g., againsta wall in the case of wall mounted enclosures), then the fixing method for the heatsinkwill be from within the case, (otherwise the enclosure would have to be removed from thewall in order to remove the heatsink).When the heatsink has been removed, the amplifier may be unscrewed from the maincasing 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 casejoint and also between the amplifier and the main case.7.3.5 Low Power Amplifier Replacement1 Disconnect the mains power supply and disconnect the 24V dc supply connector for theLPA.2 Disconnect the RF input and output cables from the LPA.3 Disconnect the alarm connector.4 Remove the alarm monitoring wires from (D type connector) pins 9 and 10.5 Remove the LPA module by removing the four retaining screws, replace with a newLPA module and secure it with the screws.6 Connect the RF cables to the LPA input and output connectors. Reconnect the wires tothe alarm board connector pins 9 and 10.7 Reconnect the DC supply connector and turn the mains switch on.Note: Tighten SMA connectors using only a dedicated SMA torque spanner. IfSMA connectors are over-tightened, irreparable damage will occur. . Do not useadjustable pliers to loosen/tighten SMA connectors.Also take care not to drop or knock the module as this can damage (or misalign in thecase of tuned passive modules) sensitive internal components. Always store the modulesin an environmentally friendly location7.3.6 Module Transportation:To maintain the operation, performance and reliability of any module it must be stored andtransported correctly. Any module not installed in a whole system must be kept in an anti-static bag or container. These bags or containers are normally identified by being pink orblack, and are often marked with an ESD label. Any module sent back to AFL forinvestigation/repair must be so protected.
