近年来,固体微波器件的发展十分迅速,已经在各类电子设备中广泛地应用。固体微波器件的发展必然会对微波电子管发生影响,一些小功率的微波管已被固体器件所取代。我们根据一些国外资料,整理出一个固体微波器件简介,供同志们参考。 1.体效应二极管: 1963年美帝IBM公司的J.B.Gunn在研究砷化镓激光器的时候,发现了微波振荡,发明了体效应二极管(又叫耿氏二极管)。这种二极管不是利用P-N结来工作的,它有一个本征半导体的有源区域。当体效应二极管加上直流偏置电压后。就在负端产生电荷层并传播通过二
In recent years, the development of solid-state microwave devices has been very rapid and has been widely used in various types of electronic devices. The development of solid-state microwave devices will inevitably affect the microwave tubes, some of the low-power microwave tubes have been replaced by solid-state devices. We based on some foreign information, sorted out a solid microwave device profile for comrades reference. 1. Effect diode: In 1963, J.B. Gunn of IBM and IBM discovered the microwave oscillation and developed the body-effect diode (also called Gunn diode) when it studied the gallium arsenide laser. This diode does not work with P-N junctions and has an active area of intrinsic semiconductor. When the body effect diode plus DC bias voltage. It produces a charge on the negative side and propagates through two
