Abstract: A switchable multi-frequency dielectric resonator oscillator that generates microwave energy at any of several available frequencies is disclosed. The oscillator includes a transistor that is operable for oscillation at a frequency determined by a feedback resonator connected to its control terminal, and switching means for selectively connecting any one of a plurality of feedback resonators to the control terminal of the transistor. The oscillation frequency of the oscillator is determined by the resonant frequency of whichever of the feedback resonators is connected to the control terminal of the transistor through the switching means. It is preferred to utilize dielectric resonators as the feedback resonators, a field effect transistor as the transistor, and PIN diodes as the switching means.

Abstract: In a differential oscillator means (535, 553, 521, 523, 549 and 551) are provided for making it possible to band switch the oscillator. This is obtained by means of cross connecting two transistors (501 and 503) and connecting inductors (509 and 511) to the transistors (501 and 503). The oscillator can be band switched by means of shortening a circuit comprising of two diodes (521 and 523). The switching time for the oscillator is very short since the oscillating circuit does not comprise any serially connected capacitors. In addition all frequency bands of the oscillator can be made impedance matched by means of adding an additional pair of varactor diodes (529 and 531).

Further, in the voltage control oscillator, a resonance circuit achieves the resonance by switching two different resonance frequencies. Moreover, inductors of a matching circuit are selectively used to change the inductance by turning on/turning off a diode of an impedance regulation circuit according to the respectively switched frequencies. Furthermore, the synthesized impedance with a matching capacitor is changed to achieve the matching with each of two frequencies.
