Three-stage 25-W225-MHz power amplifier module for FM apρlications uses three Amperex power transistors,Input and output are 50 ohms With 100-mW input signal,output is 25 W. Four capacitive dividers serve for input, output, and interstage matching. Collectors are shunt-fed. Three decoupling networks prevent seff-oscillation. Ampilfer can withstand output mismatches as high as 50:1 without damage.-E. Noll, VHF/ UHF Single-Frequency Conversion, Ham Radio, April 1975, p 62-67.
