G. TM0047 1-1 SECTION 1. GENERAL INFORMATION 1. INTRODUCTION 1.1.1 Scope of Manual - This manual is intended to familiarize service personnel working on the Dual Band Bidirectional Amplifier A300 with all pertinent aspects of the amplifier. Included in this manual are a brief physical description, a technical summary, installation information and operating data. 1.1.2 Purpose of Equipment - The A300 amplifier is used as a drop-in booster for SMR (800 MHz trunking) and PCS signals carried on 50 ohm coax cable. The amplifier will simultanously amplify signals in the SMR and PCS transmit bands in one direction and the SMR and PCS receive bands in the opposite direction. A typical use of the A300 is to provide SMR and PCS phone coverage in underground installations. 1.1.3 Physical Description - The bidirectional amplifier, shown in Figure 3-1, is designed to be mounted on a flat vertical surface. The unit has two N connectors for connection to the distribution cable and two BNC test ports to check RF signals. A 5-pin DIN receptacle is provided for local power source connection. Color coded indicators provide visual display of the unit's operating status. 1.1.4 Electrical Description - The bidirectional amplifier provides approximately 20 dB of gain for signals in the 804 - 824 MHz and 1850 - 1910 MHz bands in the direction of J1 to J2 (antenna to base) and the same amount of gain for signals in the 850 - 870 MHz and 1930 - 1990 MHz bands in the opposite direction (J2 to J1). 1.1.4.1. - The unit is locally powered through a 5-pin DIN receptacle. The P.G. Electronics PS293 power source should be used to power the unit. The unit provides DC continuity from J1 to J2 to allow powering of downstream amplifiers from upstream power sources such as PS212 and PS213. Local power is isolated from J1 and J2. 1.1.4.2. - The unit monitors bias conditions of active devices in the RF path and monitors downlink power in both bands. If one of these devices draws more or less than a predetermined limit, or if the RF downlink power is low then the FAULT indicator will go on. Under normal operating condition only the green NORMAL indicator will be on. 1.1.4.3. - If a FAULT condition is detected the unit transmits a low frequency identification code along the cable center conductor. The burst transmission is repeated at approximately 80 second intervals, while a fault condition exists. The fault reporting circuitry is powered from the cable. 1.1.4.4 - If a NORMAL condition exists in the amplifier a low frequency OK identification code will be transmitted on the cable at intervals of approximately 80 minutes. 1.1.4.5 – The unit has an adjustable attenuator in each band to allow operation at reduced gain. The attenuator is settable in 1 dB steps up to 15 dB either manually or by using an optional AUTOSET control board. P. G.

Electronics FCC ID: P6T81903 P6T81903TR Page 4 of 36 2.0 COMPLIANCE The equipment has been tested in accordance with the following performance tests and the results provided below demonstrate compliance with FCC regulations. Please refer to section 3.0 for the list of test equipment used. Notes: For all tests, the D.U.T. internal attenuator has been set to 0 dB which makes the overall unit gain equal to 20 dB. The D.U.T. was locally powered from a PS293 24 VDC power source for all tests. 2.1 Gain The gain was measured using the test arrangement as shown in Figure 2.1-1 below. Measurements were made over typical customer's bands. Network Analyzer 1 Power Coupler D.U.T. Power Coupler 10 dB Attn. Power Supply (24 V)) Figure 2.1-1 The unit gain was measured for both the SMR and PCS bands in both uplink and downlink directions. These results are shown in Plots 1 through 4 that follow. Plot 1 and Plot 2 show the SMR uplink and downlink gains respectively. Plot 3 and Plot 4 show the PCS uplink and downlink gains respectively. P. G.

Three tone intermodulation tests were performed using the equipment test arrangement in Figure 2.2-1 below. Network Analyzer 2 Network Analyzer 1 Test Set Point A Combiner Power Coupler Driver Amp D.U.T. Power Coupler Terminator 10 dB Attn. Signal Generator Power Supply (24V) Point B Spectrum Analyzer *Notes: Model A232 driver amp was used for testing. Loss from Point A (D.U.T. output) to Point B (Spectrum Analyzer input) was 10.7 dB at SMR and 11.2 dB at PCS. This includes the loss of the 10 dB attenuator, Power Coupler and cables. Figure 2.2-1 P. G. Electronics FCC ID: P6T81903 P6T81903TR Page 8 of 36 A three tone test was performed on the unit in the SMR uplink band with the input set to give the output power of +4.2 dBm for each uplink tone (+9 dBm maximum rated total inband power). The Network Analyzers were used as signal sources. The 10.7 dB loss to the spectrum analyzer results in tone levels of –6.5 dBm into the instrument. Plots 5 and 6 show the results of the test. In Plot 5, the narrower sweep setting shows in-band intermodulation products, while in Plot 6 the spectrum outside the SMR band is displayed on a broad sweep to show harmonics and spurious. The spectrum analyzer reference level was set to –6.5 dBm. A three tone test was also performed in the SMR downlink band with the input power levels adjusted to give the output power of +19.2 dBm for each downlink tone (+24 dBm maximum rated total inband power). The 10.7 dB loss to the spectrum analyzer results in tone levels of +8.5 dBm into the instrument. Plots 7 and 8 show the results of the test for both narrow and broad sweeps with the spectrum analyzer reference level set to +8.5 dBm. A three tone test was also performed in the PCS uplink band with the input power levels adjusted to give the output power of –0.8 dBm for each uplink tone (+4 dBm maximum rated total inband power). The 11.2 dB loss to the spectrum analyzer results in tone levels of –12 dBm into the instrument. Plots 9, 10A and 10B show the results of the test for both narrow and broad sweeps with the spectrum analyzer reference level set to –12 dBm. A three tone test was also performed in the PCS downlink band with the input power levels adjusted to give the output power of +19.2 dBm for each downlink tone (+24 dBm maximum rated total inband power). The 11.2 dB loss to the spectrum analyzer results in tone levels of +8 dBm into the instrument. Plots 11, 12A and 12B show the results of the test for both narrow and broad sweeps with the spectrum analyzer reference level set to +8 dBm. P. G.
