Title: Oscillator
Inventor: MAEDA KAZUYUKI
IPC: H03B5/00
Filed: 1987-02-03
Abstract: PURPOSE:To attain an oscillator using a local oscillator with less distortion thereby decreasing crosstalk by extracting an oscillated wave from a pre-stage amplifier circuit and a post-stage amplifier circuit inbetween. CONSTITUTION:The amplifier is constituted by the pre-stage and the post-stage amplifier circuits 9, 10 and an oscillated wave is extracted from a connecting point 11 between the amplifier circuits 9, 10. The oscillated wave outputted from the amplifier circuit of the post-stage is a waveform with less distortion while the harmonic is eliminated by the resonance circuit and attenuated by an attenuator to be fed back positively to the pre-stage amplifier circuit. Its level is suppressed to a degree not causing distortion by the pre-stage amplifier circuit and the pre-stage amplifier circuit is operated in the unsaturated state and the distortion caused by the pre-stage amplifier circuit is sufficiently less. Thus, the oscillated wave extracted between the pre-stage amplifier circuit and the post-stage amplifier has a small distortion.
