ABSTRACT:
An oscillator having a dielectric resonator and being electronically tuned in frequency by a varactor, in particular in the 22 GHz range, the oscillator comprising an active electronic component having negative resistance (17), at least two dielectric resonators (40, 41), and a substrate (13) on the surface of which there are three striplines (10, 11, 12), with the first and second striplines (10 and 11) being in line and having their adjacent ends connected to two respective electrodes of the active component (17). The third stripline (12) which runs parallel to the first two striplines (10, 11) is connected to the varactor (26), with all of the dielectric resonators (40, 41) being coupled to the first stripline (10).
