Abstract

PURPOSE:To make a frequency control solid oscillator small-size and stable, by constituting the line by a coaxial line and by inserting an absorber, which absorbs needless higher harmonic generated in a diode, between the internal conductor and the external conductor of this line. CONSTITUTION:Even if the double wave, the triple wave, etc. are generated by varactor diode (varactor) 13, they are absorbed by absorber 14. Consequently, internal conductor 12 of the coaxial choke line cannot be a resonance circuit, and the wave can be prevented from leaking out as a control (modulation) signal input. For original oscillation, internal conductor 12 becomes lambda/4 and constitutes a choke circuit together with a capacitance. The impedance at a sight from varactor 13 to the control signal input 8 side becomes high, so that a bad influence upon varactor 13 can be prevented.
