Abstract :
A millimeter-wave oscillator which incorporates an overmoded-waveguide resonator with an array of TE/sub 10/-mode waveguides containing Gunn diodes, has been developed as a means for achieving highly efficient spatial power combining. An efficiency of about 74% and an output power of 0.2 W (CW) at 94 GHz, has been achieved with a 3/spl times/1 waveguide Gunn diode array with dimensions of 8.1/spl times/8.2/spl times/30 mm/sup 3/.
