10kW电视发射机固态化改造

The Solid State Transformation of 10KW Television Transmitter

随着科技的发展,大功率场效应管和集成电路得到了广泛应用,使得电子管发射机向全固态发射机改造成为可能。介绍了对10kW电视发射机进行固态化改造的实例及思考,这是在广播电视向数字化过渡时期,确保安全优质播出的有效途径。

The high power field effect transistor and integrated circuit have been applied widely nowadays, moreover, the development of the high Power field effect transistor and integrated circuit technology makes it possible to transform the transmitter of radio tube into solid state transmitter. The solid-state transforming example to 10KW TV transmitter is presented in this paper. The discussion about this transformation is given in the following. It is one effective way to insure the safe and high quality broadcasting through the transition period for digitization of the broadcast television.
