BROAD BAND TUNABLE SOLID STATE MICROWAVE OSCILLATOR

摘要

Broad band tunable solid state oscillator includes a microwave frequency generating diode; a capacitance, suitably a varactor; and an open wire transmission line of either two or three spaced conductors as a frequency determining element. The line is open along its sides and is in open communication with a bounded cavity and microwave loss material is disposed in the cavity to impart a low-Q characteristic thereto. In additional aspects the foregoing elements are arranged into a compact container which integrates therewith direct current paths from the diode and varactor for connection to external DC bias voltage sources.
