Abstract : The millimeter and submillimeter wavelength oscillator includes a Gunn diode coupled to a hole in a ferrite image waveguide in such a way that a portion of the waveguide acts as a resonant cavity, and oscillation results. A coil surrounding the portion of the waveguide has a variable dc current applied to it to variably magnetize the waveguide and hence correspondingly vary the oscillator frequency. By applying an RF signal to the Gunn diode, the oscillator frequency can be mixed with the RF to yield heterodyne or intermediate frequencies.
