摘要
高频头是一种数字卫星电视信号接收装置,它能对卫星接收信号进行变频和放大。介绍一种Ku双本振多输出高频头的工作原理、性能指标、仿真结果、技术难点、实测结果,并在工程实践中实现批量化生产。
The LNBF is a kind of digital satellite TV receiving equipment which can convert and amplify the signal received by satellite. This article introduces a design of Ku-Band two local oscillators and output LNBF of Anhui Sun Create Electronics Co. , Ltd, and describes the principle, performance and indicators, the re- suhs of simulation, technical difficulties, and the results of measurement. Batch production of the LNBF was realized in practice.
