1. INTRODUCTION 1.1. Scope and Purpose of Document This handbook is for use solely with the equipment identified by the Aerial Facilities Limited (AFL) Part Number shown on the front cover. It is not to be used with any other equipment unless specifically authorised by AFL. This is a controlled release document and, as such, becomes a part of Aerial Facilities’ Total Quality Management System. Alterations and modification may therefore only be performed by AFL.
2. SAFETY CONSIDERATIONS 2.1. Earthing of Equipment Equipment 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. 2.2.
2.5. 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 dummy loads (load terminations) and some power amplifiers. These products can be identified by a yellow and black “skull and crossbones” danger symbol (shown above).

4.2. 800MHz KCRS Master Site (80-330651) Sub Components 4.2.1. 800MHz FO Master Splitter/Attenuator (55-165503) 800MHz FO Master Splitter/Attenuator (55-165503) is a 2U rack mount tray which contains attenuators and splitters.
4.2.1.1. Four Way Splitter/Combiner (05-003302) 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 should be terminated with an appropriate 50Ω load.
4.2.1.3. Dummy Load (80-007401) When a combiner system is used to split or combine RF signals, in many cases it is most cost effective to use a standard stock item 4, 6 or 8 port device where, in fact, only a 3 or 6 port device is needed. In this case the Four Way Splitters (05-003302) each have two of their ports terminated with Dummy Load (80-007401) in order to preserve the correct impedance of the devices over the specified frequency range.

5.4.1.3. Bandpass Filter (02-007206) 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 slot coupled, folded combline design, and are carefully aligned during manufacture in order to optimise the insertion loss, VSWR and intermodulation characteristics of the unit.
5.4.1.5. Switched Attenuator 0.25W, 0 - 15dB (10-000901) 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. 10-000901 provides attenuation from 0 - 15dB in 2 dB steps The attenuation is simply set using the four miniature toggle switches on the top of each unit.

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.
5.4.1.11. 12V (Single) Relay Board (80-008901) 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.
5.4.1.14. 12V Switch-Mode PSU (96-300052) 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 12.2V. The adjustment potentiometer will be found close to the DC output terminals. All the PSUs used in AFL Cell Enhancers are capable of operation from either 110 or 220V nominal AC supplies.

5.4.2.11. Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail.

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.
8.4.3.11. Dual Diode Assembly (94-100004) The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so that the main DC rail within the equipment can be sourced from either a mains driven PSU, or externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty diodes and they prevent any reverse current from flowing back to their source or the alternative supply rail.
