ABSTRACT:
A semiconductor oscillator circuit for very short waves, particularly for UHF, employing the stripline technique and utilizing capacitive voltage division in order to provide feedback. The stripline technique is employed at least, for all the discrete frequency determining (capacitive and inductive) components of the circuit and for the feedback path of the circuit. The series connection of the two capacitors forming the capacitive voltage divider is connected in parallel with a further capacitor, formed in stripline technique, whose capacitance lies in the same order of magnitude as that of one of the capacitors of the capacitive voltage divider and the two capacitors which have the same order of magnitude in capacitance are formed by two conductor electrodes which are parallel to each other at a very small mutual distance with respect to their geometric dimensions, which have a length and width corresponding to their capacitance, and which have a common return electrode.
