ABSTRACT:
A microwave evanescent-mode oscillator comprises a length of waveguide W1 having a cut-off frequency higher than the working frequency of the oscillator together with a Gunn element G disposed within the waveguide characterized in that the oscillator comprises, spaced in sequence along the waveguide a Gunn element G post-coupled into the waveguide and spaced from a first end of the waveguide, a capacitive member C and at the other end of the waveguide an end wall formed by a diaphragm D having therein an output aperture I for coupling out energy from the waveguide.
