摘要
无线电遥控技术在现代工农业生产、科研、国防等领域有非常广泛的应用，随着现代科技的发展，要求遥控技术越来越精细，需要设计者整体考虑，优化设计整个遥控系统。本文从理论上和实验上对无线电遥控发射电路和接收电路进行了系统的研究。论文主要包括两大部分，发射电路的设计和接收电路的设计，又以 发射电路的设计为重点。首先，从整体着手，阐述了整体设计思路，然后对整体方案分块设计。以求设计出最佳单元电路，然后整合在一起，使其整体电路更加精良。其次，我们开始了对各个单元电路的设计。从开关电路，到编码电路，功率放大电路，调制电路，再到发射天线，我们都一一加以介绍。最后，我们选用PT2262作编码器，F05C作发射模块，设计出一套简单、使用方便的遥控发射装置。

WIRELESS REMOTE CONTROL CIRCUIT
Abstract:
The field of radio frequency (RF)circuit design is currently enjoying a renaissance,driven in particular by the recent ,and largely unanticipaated,explosive growth in wireless telecommunications,Because this resurgence of interest in RF enigneers ,However ,in trying to synthesize the two traditions of “conventional”RF and lower-frequency IC desigers often find communication with each other difficult bacause of their diverse back-grounds and the differences in the media in which they realize their circuits .Radio-frequency IC design , particularly in CMOS, is a different activity altogether from discrete RF design.
