Abstract

This paper describes circuit techniques for obtaining wide frequency tuning capability from IMPATT and Gunn devices using varactor tuning. Using the coaxial circuit described here, an IMPATT VTO with a half octave tuning bandwidth (35%) was developed and a Gunn oscillator with a 52% bandwidth was achieved. Similar results have been reported previously by Large for a Gunn device circuit. The circuit described here applies equally well to IMPATT devices.
