Abstract:
The development is presented of a solid-state UHF power amplifier capable of delivering RF power output of two watts to the final stage of the ANGRC-103 transmitter, covering the range of 220 mc - 700 mc. The circuit used comprised both a transistor driver operating in the 87.5 - 175 mc range and varactor multipliers. A double was used for the 220 - 350 mc band, and a quadrupler for the 350 - 700 mc band. The goal of two watts power output is achieved in the lower band with a double efficiency of better than 50. The quadrupler efficiency is 25, but the required drive power of 8 watts for a 2-watt output could not be developed at 175 mc using available transistors. Coupling networks were individually tuned for maximum over-all efficiency. Author
