Efforts are being made to develop C- and X-band solid-state, pulsed- power generators. The indirect power generation technique employing a transistorized exciter and a cascaded chain of frequency multipliers was selected. The exciter output frequency has been tentatively set at 156.25 mc and the multiplier chain being considered is a cascade chain of six frequency doublers. The exciter design objectives were established and detailed investigations of oscillator stability under pulsed operation, power amplifier pulsed power gain and pulse generation techniques were initiated. An analytical treatment of oscillator load impedance variations predicts frequency stability of 1 x 10 to the -6th power for the selected configuration. The effect of junction temperature variations upon transistor power gain is treated and an expression for the maximum power output of a transistor is derived.
