Abstract
A feedback oscillator device formed with an integrated circuit having a semiconductor material substrate on a ground plane. The circuit has an amplifier having an input and an output is provided at least in part on said semiconductor material substrate. A directional coupler is used to couple the amplifier output signal to the amplifier input through a parallel separated transmission lines transfer system and a capacitor such as a varactor. The substrate can be of gallium arsenide.
Claims24
A feedback oscillator device formed with an integrated circuit, said device comprising:
- a semiconductor material substrate having a conductive ground plane on an equipotential major surface thereof on a side opposite an operating major surface thereof;
- an amplifier having an input and an output provided at least in part on said semiconductor material substrate at said operating surface thereof, said amplifier being capable of providing signals at said output thereof representative of signals occurring at said input thereof;
- and
- a coupler having an oblong input conductor of a selected input length provided on said operating surface of said semiconductor substrate electrically coupled at one end thereof to said amplifier output, and further having an oblong output conductor of a selected output length provided on said operating surface of said semiconductor substrate closely adjacent to said input conductor with said input length being substantially parallel to said output length, said output conductor being electrically coupled at one end thereof to said amplifier input.
