TRANSISTORIZED MICROWAVE OSCILLATOR OF OSCILLATION FREQUENCY MULTIPLYING TYPE

摘要

The transistorized microwave oscillator comprises an oscillating means (100) with at least a transistor (4) for oscillation and feedback means (7, 17 to 19), for generating a fundamental oscillating frequency and its harmonic components. Furthermore, there is provided a cutoff waveguide (21) connected to said oscillating means (100) for cutting off said fundamental oscillating frequency and undesired lower-order harmonics to provide a desired higher-order harmonic. A part of said feedback means (7, 17 to 19) comprises means for coupling said oscillating means (100) to said cuttoff waveguide (21). This microwave transistor oscillator is simply structured and its electrical characteristics are stable.
