ABSTRACT:
The oscillator according to the invention consists at least of: a body which has a determined geometric structure and is closed by an upper cover with a first tuning screw inserted therethrough and by a lower cover having inserted therethrough an output connector, a feed filter and preferably a second tuning screw; a resonator which is geometrically homogeneous with the said body structure and is arranged on the inner wall of the lower cover through a spacer; a microstrip also on the lower cover, arranged sideways but coupled with the resonator; a bipolar transistor or a field effect transistor; substrates preferably of fluorine polymers reinforced with fiber-glass; capacitor elements on radiofrequency block and on output by-pass; and resistances to bias, and feed the transistor and to terminate the microstrip.
