Abstract

An oscillator circuit arrangement for ultra high frequency electric oscillations comprising a transistor in common base configuration, a resonant oscillator circuit connected to the collector of the transistor which is tunable by means of a first variable capacitance diode, and a feedback path having a second variable capacitance diode whose capacitance is varied in the same sense as the capacitance of the first variable capacitance diode when the oscillator circuit is tuned, characterized in that the second variable capacitance diode is part of a parallel resonant circuit located in the feedback path, circuit that is, at least approximately, in resonance with the frequency of the oscillation generated by the oscillator circuit arrangement when tuned to the highest frequencies of the tuning range.
