Abstract
This paper describes the design and performance of an all-solid-state amplifier, which provided 29.5 dB of gain and 9.1 watts of CW output power in the 100-MHz band from 2.2 to 2.3 GHz. The technique used to measure optimum source and load impedances of a class-C transistor at microwave frequencies is shown. A comparison is made of the performance of several single-stage coaxial class-C designs. Attempts to combine several stages at a scale frequency of 1.15 GHz, using both direct paralleling and hybrid-combining, are discussed. Finally, the results obtained in hybrid-combining sixteen stages to obtain the 9.1 watts of CW output are shown.Keywords
