卫星通信地球站收发射频设备技术性能指标浅释（二）--地球站天馈设备性能技术指标浅释

摘要

射频设备，包括天线、接收机、发射机，是卫星通信地球站的重要组成部分，决定了通信链路的传输性能，为了保证好的通信质量、可靠性和电磁兼容性，对RF设备给出了严格的规定，构成了一整套技术指标体系，本讲座将阐明这些指标的定义和内涵，并给出案例。%RF equipment, including antenna and transceiver, is an important part of a satellite communications earth station. It determines the performance of a communication link. To guarantee good communication quality, reliability and electromagnetic compatibility, strict regulations for RF equipment are made, and a complete set of technical performance speciifcations is constructed. In this series of lectures, we will explain deifnitions and content of these technical speciifcations, and give examples in practical applications.
