UHF RF Power amplifier functional description

Ex Ministry of defence Marconi UHF RF power amplifier theory of operation & functional description. We look at the design, how the circuit functions in the signal path, the biasing of RF Transistors, wilkinson & doherty combiners & signal transformers & balun's, transmission line tuning & pub layout of the RF devices & their multistage impedence matching & RF power sniffing & directional couplers.
