【 摘 要 】

Multi-elements oscillators with a quasi-optical res- onator are reported. The resonator consists of a Fabry-Perot cavity with a grooved mirror and con- cave mirror. The oscillator has capability for power- combing of solid-state sources in the millimeter and submillimeter wave region. X-band models con- sisting of Gunn diodes or GaAs MESFET's have been demonstrated. Coherent power combining and frequency-locking of 18 diodes (6x3 grid) and 6 FET's(la grid) have been successfully observed at X-band. We have also succeeded frequency-locking of 3 Gunn diodes at U-band. A W-band InP Gunn diode oscillator using a same configration is also reported.
