Multiple-frequency operation and other characteristics of quenched-domain, Gunn-effect devices

In an earlier paper the authors reported the experimental verification of an analytical model for the high-frequency, quenched-domain (circuit-controlled) mode of Gunn-effect devices. The application of this model to multiple-frequency operation will be reported accompanied by supporting experiments. It will be shown that these devices can be used for microwave amplification in a new manner harmonic generation and frequency downconversion and upconversion. The theoretical results include the effects of second harmonic and subharmonic signals on the quenched-domain mode and the effect of the nol product (carrier demity times crystal length) upon efficiency and operating characteristics.
