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.
