本文档是调频发射机与调频接收机的设计报告。介绍了调频无线通信系统的原理计算、性能指标、设计方案、调试过程等内容，是通信基本电路实验的系统性总结。该系统分为发射机和接收机两部分。调频发射机由振荡级，缓冲级，功放级组成，级联并采用变容二极管部分接入电路的方法进行直接调频。调频接收机为以SONY公司的CXA1619BM/BS芯片为核心元件的电路。本系统可实现5～10米内调频数据、语音通信功能。-This document is the design report of a FM transmitter and a FM receiver. It describes the FM wireless communication systems theory, performance, design, and debug processes, which a systemic summary of the course Experiment of Basic Circuit of Communication. The system is divided into two parts transmitter and receiver. The FM transmitter consists of a oscillator, a buffer and a power amplifier, which uses a varactor diode for directly FM, with three circuits cascaded. The receiver is accomplished with the core chip CXA1619BM/BS by SONY. The system can perform a 5 to 10 meters FM data and voice communication.
