Abstract
An electronic oscillator of a circuit arrangement for creating microwave oscillations with two transistors as amplifier elements and with a resonator (), wherein the resonator has two emitter impedance networks, the base impedance network and/or an emitter impedance network or both emitter impedance networks can be put out of tune and the transistors each have a parasitic base collector capacitance. The repercussion of the load on the electronic oscillator ('load-pulling') is greatly reduced so as to be eliminated as much as possible, in that a compensation capacitance is switched between the collector of the first transistor and the base of the second transistor as well as between the collector of the second transistor and the base of the first transistor, and the compensation capacitances are implemented by reverse-biased pn-junctions.
