OVERVIEW/SYSTEM DESCRIPTION The AFL Band Selective Cell Enhancer is a 2-way on-band repeater. Various models are available to cover frequency bands from 50MHz to 3000MHz with power levels up to 100Watts. 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 Band 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 or leaky feeder 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. This system consists of a bi-directional band selective, cell enhancer operating in the 390MHz band. It is housed in a wall-mounted environmentally protected (IP65) case powered from an externally supplied 24Volt DC source. Alarms are provided for each amplifier as a summary, volt-free relay contact pair for easy integration into an existing alarm system. A supply isolator switch is fitted inside the unit and there are D.C. and Alarm on indicators on the outside of the door. An automatic gain control system is employed in the uplink path in an attempt to negate the overloading effect from mobiles operated close the antenna.

Technical description Bandpass Filters & Duplexer (02-007306 & 16-041401) 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 silver-plated 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. 1.2 Technical Specification (02-007306) PARAMETER SPECIFICATION Response type: Chebyshev Frequency range: 350 – 500MHz (tuned to spec.) Bandwidth: >5.0 MHz (tuned to spec.) Number of sections: 5 Insertion loss: 1.2 dB VSWR: better than 1.2:1 Connectors: SMA Power handling: 100W max operation: -10°C to +55°C Temperature range storage: -40°C to +70°C Weight: 3 kg Size: 266 x 143 x 39.5mm 1.3 Technical Specification (16-041401) RX Pass Band: 380-385MHz TX Pass Band: 390-395MHz Bandwidth: 5 MHz Channel Separation: 5 MHz Insertion Loss: < 1.8 dB Rejection (between channels) >70 dB Rejection at crossover: >50 dB (+2.5MHz low band -2.5MHz high band) Return Loss: > 20 dB (at all ports) Power Handling (CW): 20W SMA (Tx/Rx ports) Connectors: N type (Antenna ports) Weight: <6kg 2 ¼Watt 0- -30dB Switched Attenuator (10-000701) 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. 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 50Ω impedance over their operating frequency at both input and output. 3 Low Noise Amplifiers (11-007302 & 11-007402) 3.1 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 two active devices are very moderately rated to provide a long trouble-free working life. There are no adjustments on these amplifies, and in the unlikely event of failure then the entire amplifier should be replaced. 3.2 Technical Specification, 11-007302 PARAMETER SPECIFICATION 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: <300gm Size: 90 x 55 x 30.2 (case only) 3.3 Technical Specification, 11-007402 PARAMETER SPECIFICATION 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 Weight: <300gm Size: 90 x 55 x 30.2 (case only) operation: -10°C to +55°C Temperature range: storage: -30°C to +70°C 4 1Watt Low Power Amplifier (11-007901) 4.1 Description This amplifier is designed as a 1.0 W driver from 380 MHz to 470 MHz for the 10W output amplifier. It is a 2 stage amplifier where each stage is in balanced configuration. It demonstrates very high linearity and good input/output VSWR. There is a Current Fault Alarm Function, which indicates failure of each one of the RF transistors by various alarm output options. The amplifier is housed in an aluminium case (Alocrom 1200 finish) with SMA connectors for the RF input/output and a 9way D-type connector for DC and alarm outputs. 4.2 Technical Specifications PARAMETER SPECIFICATION Frequency range: 380-470MHz Small signal gain: 37.5dB Gain flatness: ±0.5dB Gain vs. temperature: 1.5dB operational: -10°C to +55°C Temperature range: storage: -40°C to +70°C Input/output return loss: 18dB Maximum output power: 30.4dBm (@ 1dB comp. point) OIP3: 43dBm Supply voltage: 10-15V DC Current consumption: 780mA (typical) Noise Figure: <1.75dB 5 10W Power Amplifier (12-016302) 5.1 Description This amplifier is a Class A 10W power amplifier from 380MHz to 470MHz in a 1 stage balanced configuration. It demonstrates a very high linearity and a very good input/output return loss (RL). It has a built-in Current Fault Alarm Function. Its housing is an aluminium case (Alocrom 1200 finish) with SMA connectors for the RF input/output and a D-Type connector for the power supply and the Current Fault Alarm Function. 5.2 Technical Specification PARAMETER SPECIFICATION Frequency range: 380-470MHz Small signal gain: 23dB Gain flatness: ±1.7dB I/O Return loss: >18dB 1dB compression point: +40dBm OIP3: +52dBm Supply voltage: 24V DC Supply current: 2.6Amps (Typical) operational: -10°C to +55°C Temperature range storage: -30°C to +70°C Weight: <2kg (no heatsink) 6 Dual DC/DC Converter (13-001803) 6.1 Description This unit is employed where it is necessary to derive two fixed voltage power supply rails from some higher voltage. Typically it is used to derive 5, 8, 12 or 15V from a 24V input. The circuit is based upon a pair of LM257 series variable voltage regulators (LM2576, 12 & 15V & LM2575, 5V), which are each capable of supplying an absolute maximum of 1.5A output current. Note that at full output current, the dissipation of the device must remain within design limits, bearin…
