ABSTRACT:
A voltage controlled oscillator of the type wherein a variable capacitance diode is connected in parallel with a distributed parameter line functioning as a resonance circuit, whose capacitance varies in response to voltage control. To vary the resonance wavelength of the distributed parameter line a condenser is connected in series therewith, and the condenser is short-circuited by a switching diode. A coaxial dielectric line, strip line, coaxial cable, etc. may be used as the resonance circuit element by dividing the distributed parameter line into two parts and employing these elements as the divided parts.
