HETEROJUNCTION BIPOLAR TRANSFERRED ELECTRON TRIODE AND VOLTAGE-CONTROLLED FREQUENCY VARIABLE OSCILLATOR, INJECTION-LOCKED OSCILLATOR, SELF-OSCILLATION MIXER, AND RECEIVER USING THE ELECTRON TRIODE

摘要

PROBLEM TO BE SOLVED: To reduce base and thermal resistance, and at the same time to obtain high oscillation output power.;SOLUTION: A cathode layer is divided into a first and second cathode layers 28 and 29. The interval between both cathode layers is set to two times or less larger the thickness of an active layer 26, and at the same time electrical connection is made for substantially increasing the area of the cathode layer, thus overlapping guide mains that are generated in the active layer 26 directly below the cathode layers 28 and 29, mutually connecting electric fields, generating synchronized propagation and oscillation, and obtaining high oscillation output power. In this case, each of the cathode layers 18 and 19 can be set to nearly the same size and shape as the conventional one, and increase in the base and thermal resistance can be inhibited.;COPYRIGHT: (C)2002,JPO
