| Abstract(in English) | A millimeter-wave oscillator which incorporates an overmoded-waveguide resonator with an array of TE_<10>-mode waveguides containing Gunn diodes, has been developed as a means for achieving highly efficient spatial power combing. The oscillators with a 3×3 waveguide Gunn diode array have achieved a power combining efficiency more than 83% and an output power of 1.5W (CW) at 61 GHz, and 51% and 0.45 W (CW) at 98.8 GHz, respectively . A noise reduction effect in power combining type oscillators has been observed for the oscillators with nine Gunn diodes, as predicted by theory. |
