Abstract
An equivalent circuit for designing a coherent power combiner using a quasi-optical resonator has been developed. In the resonator, large nu mbers of devices (HEMT, HBT, etc.) are arrayed two dimensionally and m ounted on a surface of a metal grooved-mirror. A newly developed equiv alent circuit for the resonator has been constructed using a transmiss ion-line model. Experiments performed at Ku-band have shown that oscil lation frequencies in a 3x3 HEMT array oscillator can be predicted wit h errors of less than 1% by using this equivalent circuit.
