Uses Motorola of transistors optimized for 12.5-V FM operation. All stages are class C. Signal-splitting techniques in input and output matching networks of power output stage minimize problems of unequal load sharing and of matching to extremely low impedance levels. Overall gain is 26 dB, and efficiency is 49.5%.-J. Hatchett, Design Techniques for an 80 Watt, 175 MHz Transmitter for 12.5 Volt Operation, Motorola, Phoenix, AZ, 1972, AN-577, p 2.
