ABSTRACT:
A microstrip circuit which features a pair of open ring resonators sections adapted to oscillate independently in their even mode. In a preferred form, the ring resonator sections are each driven by a TRAPATT diode, and include a load circuit which combines the individual power outputs to a common load. Tuning stubs and the like may be provided to reactively trap harmonics in order to initiate the desired TRAPATT mode, and additional ring resonators may be interposed between the driving circuit and the load to filter the fundamental frequency, if desired. Other configurations permit power to be combined from two or more sets of dual ring resonators.
