Abstract

PURPOSE:To improve the stability of operation and also to widen its range by inserting an isolator, functioning at a N-order higher harmonic frequency, between an oscillation circuit part and filter. CONSTITUTION:An isolator or circulator 8 operating in the N-order higher harmonic frequency band of a fundamental oscillation frequency, the output signal frequency of an oscillation multiplication type microwave generator, is provided between filter 7 and an oscillation part composed of transistor 1, resonator 5 and electric-field or magnetic-field coupling circuit 6. Consequently, the stability of the operation of a microwave band transistor oscillating multiplier can be improved and its wide band can also be realized.
