ABSTRACT:
A high-frequency oscillator having a high-frequency oscillation circuit formed through use of a microstripline. The high-frequency oscillation circuit has a resonator and a transistor connected to a reference potential and coupled with the resonator through a first capacitor. A first electrode of the transistor is connected with the resonator through the first capacitor. A second electrode of the transistor is connected to the reference potential and a third electrode thereof is adapted to derive an output. A substrate is provided with a land portion to be connected with the first electrode of the transistor, and a capacitor electrode is formed on the opposite surface of the substrate to be opposite to the first electrode connection land portion through the substrate. The capacitor electrode, the first electrode connection land portion and the substrate form a second capacitor, which is connected to the reference potential between the first capacitor and the first electrode of the transistor.
