Abstract

A high frequency oscillator has a substrate made of, for example, a dielectric material, a resonator circuit disposed on one principal surface of the substrate and formed of a finite-length coplanar line having a signal line and a ground conductor arranged along the signal line on both sides thereof, a negative resistance element for connecting between the signal line and the ground conductor, and an output line routed on the other principal surface of the substrate and electromagnetically coupled to the resonator circuit through the substrate. A Gunn diode is preferably used for the negative resistance element, and is connected, for example, in a substantially central region of the signal line. The output line preferably forms a microstrip line structure together with the ground conductor.
