基于RF2052射频芯片的宽带下变频电路设计与实现
资料介绍
本文首先对卫星广播通信地面接收机现有的变频结构作了简要的介绍，对其关键技术指标进行了深入的分析，并根据某卫星广播通信地面接收机的技术要求，提出了该接收机变频系统的设计方案并对该方案进行了可行性分析与论证。该方案的主要特点是在满足设计指标的同时节省了后端器件的成本，降低了基带信号处理器的程序设计复杂度。
Initially, the existing frequency conversion structure of the satellite communication land receiver is brielly introduced in this article, and the crucial technical data of the frequency conversion are deeply analyzed. Furthermore, according to the technical requirements of some satellite communication land receiver, the design scheme of the receiver＇s frequency conversion system is pro- posed, and then the feasibility analyzing and verifying for this scheme is implemented. The main characteristic of the scheme is that the cost of the back-end device can be economized while the design index is satisfied, thus the programming complexity of the base- band signal processor is reduced.
