DEVELOPMENT OF C- AND X-BAND POWER GENERATORS
Abstract
Implementation of the indirect power generation technique employing a transistorized exciter and a cascaded chain of six frequency multipliers was continued during this period. The feasibility of obtaining a transistorized exciter output of 60 w at 156 mc to drive the cascaded chain of frequency multipliers was verified. Design of the intermediate- and high-power amplifiers was completed. Marriage testing of the transistorized exciter modules was performed and the desired power output of 60 w was achieved using the breadboard models. The bridge-type circuit was successfully implemented in the lumped-element and distributed-element harmonic generators. A conversion efficiency of -1.75 db was obtained for a four-diode bridge doubler with an output power of 27.2 w at an input frequency of 156 mc; a conversion efficiency of -3.8 db has been obtained for a two-diode bridge doubler circuit with an output power of 3.3 w at an input frequency of 1.25 gc. Efforts to increase the efficiency of the high-frequency multiplier are continuing.
