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.
