The amplifier uses the internally matched MRF844 transistor in a mon base Class C configuration providing a minimum of 5.0 dB gain over a fixed tuned bandwidth of 800 to 870 MHz at 12.5 volts. Lower manufacturing costs are of prime concern to land mobile equipment suppliers and single-board, fixed tuned transmitter amplifier designs are being increasingly mon. Two versions are...
