摘要
高功放是地球站播出系统关键传输设备,目前,广东卫星地球站速调管高功放使用时间长,逐渐老化,存在播出隐患,因此提出速调管高功放固态化改造需求.从速调管高功放和固态高功放的各方面进行比较,阐明固态高功放的优点,通过计算确定固态高功放的功率需求,根据广东卫星地球站的客观情况,制定速调管高功放固态化改造技术方案.
Abstract
High-power amplifier is a key transmission equipment in the broadcasting system of the Earth Station.Currently,the high-power amplifier of the Guangdong Satellite Earth Station's klystron has been in use for a long time and is gradually aging,which poses broadcasting risks.Therefore,the demand for solid-state transformation of the klystron high-power amplifier is proposed.This article compares the various aspects of klystron high-power amplifier and solid-state high-power amplifier,classifies the advantages of solid-state high-power amplifier,determines the power demand of solid-state high-power amplifier through calculation,and develops a solid-state transformation technology plan for klystron high-power amplifier based on the objective situation of Guangdong Satellite Earth Station.
