引言出于经济上的原因,特别是随着能源成本的增加,迫使电子功率管的设计者们经常修改目前通用的设计,并对以前的某一种管型进行反复的调查研究。最近,国外经过反复的研究,对一种非常老的和普遍为人们所忽略的器件进行了改进和更新,终于制成了一种新管型。这种器件在超高频范围内可以作为从10千瓦到100千瓦的功率发生器,该器件用于电视中具有其特殊的优点。管子本身的结构图1是一种管子的简图,这种管子是一种具有图盘状阴极、平面栅极和开孔阳极的五元件的器件。重入式的腔体装在阳极和被称为后
Introduction For economic reasons, especially as energy costs have increased, designers of electronic power tubes have been forced to make frequent changes to their current designs and to conduct repeated investigations of a previous type of tube. Recently, after repeated studies abroad, a very old and generally ignored device has been improved and updated, and finally made a new type of tube. This device can be used as a power generator in the UHF range from 10 to 100 kilowatts and has the special advantage of being used in a television. Structure of the tube itself Figure 1 is a simplified schematic of a tube that is a five-element device with a disk-shaped cathode, a planar grid and an open-celled anode. Reentrant cavity mounted on the anode and called rear
