UHF BI-DIRECTIONAL AMPLIFIER TECHNICAL MANUAL 4 Class B Amplifier Box Description 1) This Amplifier is designed around the philosophy of Anytime, Anywhere, and Anyplace and uses Class “AB” Amplifiers, designed for a more constant and reliable Amplifier unit. Designed to be used in buildings, tunnel, government facilities, airports, providing the communication throughout. Typically, the Amp box will be connected to either radiant cable or a distributed antenna system. (Example below) 2) An Amplifier box is used increase the coverage of RF communications in buildings or places were RF is unable to penetrate from the base station site. UHF BI-DIRECTIONAL AMPLIFIER TECHNICAL MANUAL 5 Specifications Our UHF amplifier have been designed with government agencies in mind. These are our highest level of performance and quality for continuous duty solutions while providing maximizing coverage. Available in rack mount, nema stainless steel, or painted steel nema enclosures. Block Diagram Details - The Downlink path receives signals from the donor antenna, and then amplifies them as they pass through the unit to the distribution system. - The Uplink path receives signals from the distribution system, and then amplifies them as they pass through the unit to the donor antenna. - Uplink and Downlink paths contain each a Variable Gain Amplifier (VGA) followed by a fixed gain Power Amplifier (PA). A mid-stage access allows channel filter to be inserted, in order to reject adjacent channel signals and to improve the main signal quality. - The VGA is basically a low noise amplifier featured Automatic Gain Control (AGC) circuit . The AGC circuit measures composite power level at the VGA input and adjusts automatically the gain, in order to maintain constant the signal level at the VGA output. Since the VGA output power is constant, the PA composite output power is also maintained constant at the factory set level. - The VGA provides also Input Level Adjustment and Output Power Setting by mean of two Manually Set Attenuators (MSA#1 and MSA#2). The MSA#1 allows additional attenuation and hence maintains the VGA under linear condition if the input signal is too strong ( greater than -25dBm). It is also used for adjusting the input signal to the optimum level (please see VGA Max Input Level and Optimum Input Level Setting ). The MSA#2 attenuator allows to adjust the VGA power, thus the PA output power can be also changed to the desired level, which can be differed to the factory set level. An MSA#2 setting table vs. VGA output power is supplied with the unit. The PA linear gain is also provided. - The Class-AB PA provides good performance for both linearity and efficiency. This amplifier is heat sink mounted and produces a high compression point and 3 rd order Intercept point. - The Power Supply bloc converts AC to DC voltages for supporting DC power needs of both Uplink and Downlink amplifiers. - The unit can accept 50/60Hz 100 to 260 Volt AC power source, but does not have UPS/Battery system. In case of need for inconsistency in the AC line power, surge protection, short Black outs, crossover time from line AC to generator power, circuit breaker for short circuit and over load protection, etc., an external UPS/Battery system is recommended. UHF BI-DIRECTIONAL AMPLIFIER TECHNICAL MANUAL 6 Figure 1: Bloc diagram of the UHF Amplifier with external filter/diplexer connection UHF BI-DIRECTIONAL AMPLIFIER TECHNICAL MANUAL 7 VGA Max Input Level and Optimum Input Level – MSA#1 Setting The VGA can maintain constant its output power for any composite input level from –60 to -25dBm. If the input level is too high, the MSA#1 must be used to provide additional attenuation, then decrease the input signal to the correct level. The MSA#1 attenuation can be set from 0 to 30dB per 2dB step, by mean of a hexadecimal switch (16 positions from “0” to “F”). When it is possible, it is recommended to set the nominal input power to -40dBm, such a setting allows maximum dynamic range of the AGC circuit, and the VGA output power will be constant even if several sub-carriers are suddenly added on or dropped from the main signal. The VGA displays two RSSI LED (Received Signal Strength Indicator LED) labeled HI and LOW. When both LED are on, the input composite power should be with-in the optimum range, .i.e. -42 to - 38dBm. Thus, if the received nominal input power is ranging from -42 to -8dBm, it is possible to set the VGA input to the optimum level, by changing the MSA#1 setting from 0 to 30dB of attenuation. If the received nominal level is lower than -42dBm, the MSA#1 should be set at 0dB attenuation. Table I: MSA#1 and MSA#2 attenuation versus Hexadecimal Rotary Switch Position Dial MSA #1 Att.

This Factory set gives the maximum operable power, therefore the unit must not be re-adjusted for giving higher output. However, re-adjusting for lower output power…
