1. 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.
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).
2. OVERVIEW/SYSTEM DESCRIPTION The AFL 800MHz Off Air Amplifier for the Pasadena Blue line project is an 8 way channelised RF amplifier. It’s application is as an air interface between the donor radio site and the tunnel leaky feeder system. The 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.

5. SUB-UNIT MODULES 5.1 5.1.1 Bandpass Filter (02-011601) 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.
5.2 5.2.1 2-Way Splitter/Combiner (05-002602) Description The Splitter/Combiner used is a device for accurately matching two or more RF signals to single or multiple ports; most usually within a specified frequency band, whilst maintaining an accurate 50Ω load to all inputs/outputs and ensuring that the VSWR and insertion losses are kept to a minimum. Any unused ports will be terminated with an appropriate 50Ω load. 5.2.
5.3 5.3.1 4-Way Splitter/Combiner (05-003302) Description The Splitter/Combiner used is a device for accurately matching two or more RF signals to single or multiple ports, whilst maintaining an accurate 50Ω load to all inputs/outputs and ensuring that the VSWR and insertion losses are kept to a minimum. Any unused ports will be terminated with an appropriate 50Ω load.
5.5 Low Noise Amplifiers (11-005902 & 11-006702) 5.5.1 Description The Gallium-Arsenide low noise amplifiers used in the unit are double stage, solid-state low noise amplifiers. 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.

5.7 5.7.1 3 Stage Alarm Board (12-002201) 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.

5.8 5.8.1 DC/DC Converter, 24V in, 12V 8A out (13-003011) 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/back panel 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.
5.9 5.9.1 Channel Control & Channel Selective Modules (17-002101 & 17-009127) 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.
5.9.2 Drg. Nō.
5.9.3 Channel Control Module Description The control module consists of a bank of four, in-line data switches each of which control one channel module frequency setting. One controller unit can therefore control four channel modules. The following list shows the frequencies available for each switch setting. 5.9.

5.11 24V 400W Flat-Pack Power Supply (96-300011) 5.11.1 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.
6. 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 unit means that it represent a significant health hazard unless it is mechanically installed in the correct manner.
6.5 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 are detailed in the whole system diagram in section 4.
7. MAINTENANCE 7.1 7.1.1 General Procedures 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.
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.
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. 7.1.6 Service Support Advice and assistance with maintaining and servicing this system are available by contacting Aerial Facilities Ltd. 7.
7.3 7.3.1 Care of Modules 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.
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.
