Abstract

The grooved-mirror-type Fabry-Perot (GFP) oscillator was used for coherent power-combining of multiple elements in the millimeter- and submillimeter-wave region. The admittance of the Gunn diode in oscillation was measured experimentally in the millimeter-wave region to design the GFP oscillator. The gain characteristics of the diode were found at the frequencies from 42 to 48 GHz from the measured results. With this Gunn diode in the GFP resonator, oscillation was observed. The experimental results indicated that for impedance matching between the diode and the resonant cavity, the groove height must be adjusted
