5-Way Channelised UHF Cell Enhancer Maintenance Handbook H/book Number:-50-060601HBKM Issue No:- 1 Date:-04/07/2003 Page:- 10 of 54 2.OVERVIEW/SYSTEM DESCRIPTION The AFL Channel Selective Cell Enhancer is a 2-way on-band repeater. Various models are available to cover frequency bands from 50MHz to 3000MHz. Its main sphere of applications is in urban areas where the topology is such that shadows occur in the propagation pattern (for example within large buildings, conference centres and tunnels, etc.,) The Channel Selective Cell Enhancer is a 2-port device for direct connection to two antennas, usually a highly directional Yagi or similar aligned towards the base (donor) site and an omni-directional antenna to cover the mobiles. The frequency bands that are passed by the Cell Enhancer are set as per the specific customer requirements. AFL manufacture a wide range of Cell Enhancers, configured for each customer's specific requirements. Two basic physical variants are available, a rack mounted version to fit in a standard 19" rack and an environmentally sealed wall mounted version which requires no further enclosure. The rack-mounted version is usually supplied in 3 units, a power supply unit and 2 RF units (one containing each path). Each shelf/tray unit containing active modules has a ‘D.C. on’ indicator on the front panel and the PSU also has an ‘A.C. on’ indicator. The wall-mounted version is supplied in a single environmentally-protected case. Handles are provided for carrying the unit and the door is fitted with locks. A supply isolator switch is fitted inside the unit and there are ‘.DC. on’ and ‘Alarm on’ indicators on the outside of the door.

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 silver-plated to reduce surface ohmic losses and maintain a good VSWR figure and 50Ω 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. 5.1.1.2 Technical Specification PARAMETERSPECIFICATION Passband 453-454 MHz Insertion Loss 1.9 dB typical > 456 MHz > 55 dB Rejection > 458-459 MHz > 60 dB Power Rating 50 Watt Impedance 50 ohm VSWR Better than 1.2:1 5-Way Channelised UHF Cell Enhancer Maintenance Handbook H/book Number:-50-060601HBKM Issue No:- 1 Date:-04/07/2003 Page:- 20 of 54 5.1.2 UHF 3dB Splitter (05-002603) 5.1.2.1 Description The 3dB 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. 5.1.2.2 Technical Specification PARAMETERSPECIFICATION Frequency Range: 380 - 520 MHz Bandwidth: 140 MHz Inputs: 1 Outputs: 2 Insertion Loss: 3.5 dB (typical) Isolation: >18 dB Return Loss (VSWR) – Input: Better than 1.3:1 Return Loss (VSWR) – Output: Better than 1.3:1 Impedance: 50 ς Power Rating – Splitter: 20 Watts Power Rating – Combiner: 0.5 Watt Connectors: SMA female Size: 54 x 44 x 21 mm (including connectors) Weight: 200 g 5-Way Channelised UHF Cell Enhancer Maintenance Handbook H/book Number:-50-060601HBKM Issue No:- 1 Date:-04/07/2003 Page:- 21 of 54 5.1.3 3dB UHF Splitter (05-002603) 5.1.3.1 Description The 3dB 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. 5.1.3.2 Technical Specification PARAMETERSPECIFICATION Frequency Range: 400-500 MHz Power Rating: 5 Watts Insertion Loss: 5.2dB Typical VSWR: 1.2:1 Impedance: 50 Ohms Connectors: SMA Weight: <0.5Kgs Mechanical: Drawing No. 07-003890 5.1.4 ¼Watt 0- -30dB Switched Attenuator (10-000701) 5.1.4.1 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. 5.1.4.2 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 50Ω impedance over their operating frequency at both input and output. 5-Way Channelised UHF Cell Enhancer Maintenance Handbook H/book Number:-50-060601HBKM Issue No:- 1 Date:-04/07/2003 Page:- 22 of 54 5.1.5 Low Noise Amplifiers (11-007302 & 11-007402) 5.1.5.1 Description The low noise amplifiers used are double 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. The two amplifiers are very similar in construction, the only difference is the biasing, which changes the gain figure, see tables below. 5.1.5.2 Technical Specification, (11-007302) PARAMETERSPECIFICATION Frequency range: 380-500MHz Bandwidth: <140MHz Gain: 20-22dB 1dB Compression Point: +23.5dB (typical) 3rd order intercept: +36dB (typical) Input/Output return loss: >20dB Noise figure: <1.3dB Connectors: SMA female Supply: 200-230mA @ 24V DC operational: -10°C to +55°C Temperature range: storage: -30°C to +70°C Weight: <300gms Size: 90 x 55 x 30.2 (case only) 5.1.5.3 Technical Specification (11-007402) PARAMETERSPECIFICATION Frequency range: 380-500MHz Bandwidth: <140MHz Gain: 30-32dB 1dB Compression Point: +22dBm (typical) 3rd order intercept: +34-35dBm (typical) Input/Output return loss: >20dB Noise figure: <1.3dB Connectors: SMA female Supply: 300-330mA @ 24V DC operational:-10°C to +55°C Temperature range: storage: -30°C to +70°C Weight: <300gms Size: 90 x 55 x 30.2 (case only) 5-Way Channelised UHF Cell Enhancer Maintenance Handbook H/book Number:-50-060601HBKM Issue No:- 1 Date:-04/07/2003 Page:- 23 of 54 5.1.5.3 Drg.
