The operation principle and the design method of Distributed Bragg Reflector Gunn oscillators in the millimeter waveband are described based on the theory of coupled-modes in a dielectric grating region, the oscillator is constructed by an inverted-strip dielectric waveguide and an inserted Gunn diode. A practical oscillator with an output of 60~90 mW and 10/sup -5/~10/sup -6/ frequency stability at 36 GHz has been performed, the test results are in agreement with theoretical predictions.
