CWWP310KL1C9UPAMPLIFIER

Power Amplifier Users Manual 1. General Information. 1.1. The Power Amplifier (PA) is a C-class unit. It is intended for amplification of single carrier phase (frequency) modulated narrowband signals. 1.2. PA is intended to work with a radio, operated in simplex mode using a switching bypass relay. 1.3. The single amplifier covers both frequency ranges 896.8875-897.9875 MHz and 935.8875-936.9875 MHz. 1.4. Nominal output power is 30 W and nominal gain is 5 dB with 10 W input power. 1.5. Working input power range is 10 W - 15W. 1.6. Input VSWR is not greater than 2:1. 1.7. DC power supply voltage range is 13.0 – 13.6 V. 1.8. DC current consumption is not greater than 9 A. 1.9. The base plate temperature range is -30ºC to +70ºC. 1. Caution: Be very careful to not stress the 13.6 VDC red wire/filter interface near the two rf connectors. 2. The Power Amplifier (PA) should be screwed to a flat surface of massive metal construction that is able to serve as its heatsink. A good thermal contact between the lower base of PA chassis and heatsink must be provided (a thin layer of thermal grease is highly recommended). Take care that all dirt and dust has been removed before screwing the PA to the mounting surface. 3. The red DC wire should be connected to + 13.6 VDC line; black (return) DC wire should go to ground. The amplifier is protected against reverse voltage polarity (it shorts a circuit with the wrong polarity) but for time not greater than 0.3 sec. 3. The nominal DC power supply voltage should be 13.6 V. 4. RF input power shall be in limits 10 W – 15 W within the over the specified frequencies and should not exceed 2 W outside this range. 5. Output load VSWR shall not exceed 2:1. 6. It is recommended to keep the temperature of heatsink in the place of PA installation less then +70°C. The unit has an overheat protection that activates and blocks switching to transmit mode when the lower base temperature reaches +85°C. The unit returns to normal operation when the temperature drops to approximately +70°C. 7. The unit is designed for a transmit/receive duty cycle up to 1:4 with the transmitting duration not greater than 1 min.

STANDARD TEST CONDITIONS Except as noted herein, the following conditions and procedures were observed during the testing: In accordance with ANSI C63.4-1992/2000, section 6.1.9, and unless otherwise indicated in the specific measurement results, the ambient temperature of the actual EUT was maintained within the range of 10 to 40 degrees C (50 to 104 degrees F) unless the particular equipment requirements specify testing over a different temperature range. Also, unless otherwise indicated, the humidity levels were in the range of 10% to 90% relative humidity. Prior to testing, the EUT was tuned up in accordance with the manufacturer's alignment procedures. All external gain controls were maintained at the position of maximum and/or optimum gain throughout the testing. Measurement results, unless otherwise noted, are worst-case measurements. Temperature: 89.5°F Humidity: 51% 4.

The following measurements were performed with an Amplifier Research Field Probe using ANSI/IEEE C95.1 as a guide. 2. Prior to making any measurements, the measurements system was calibrated in accordance with the manufacturer’s procedures. 3. The EUT’s radiating element (antenna) was placed on a wooden table 80 cm high. The vertical whip antenna was mounted in a typical operational manner. 4. The remaining equipment necessary to operate the EUT was maintained at a distance from the measurement arrangement suitable to minimize interference with the measurements. 5. The minimum safe distance was calculated from the formula Power Density = EIRP /4חR² (Peak Watts/m²). The calculation is shown with the measurement data. 6. With the EUT operating at maximum power, a search was initiated for worst case emissions with the probe raised and lowered over a range 0 o 140 cm height range. plane of 0 to 360 degrees. Worst case emissions were found to be at point perpendicular from the antenna base and were the same at different axes. 7.
