摘要

本文给出了863-870 MHz欧洲频段无线传感器用跳频扩频收发器接收机部分的仿真结果。该接收机设计用于二进制移频键控(BFSK)调制，通信最大数据速率为20 kb/s。接收机由低噪声放大器和下变频混频器、低通通道选择滤波器和限幅器组成。对接收机的噪声系数、增益和IIP3等各模块参数进行了仿真和优化，以满足接收机的规格要求。接收机仿真结果显示，转换增益为51.1 dB, IIP3为-7 dBm，回波损耗(S11)为-15 dB, NF为10 dB

A 863-870-Mhz spread-spectrum direct conversion receiver design for wireless sensor

This paper presents simulation results of the receiver section of a frequency-hopped spread-spectrum transceiver operating in the 863-870 MHz European band for wireless sensor applications. The receiver is designed for binary frequency-shift keying (BFSK) modulation, communicating a maximum data rate of 20 kb/s. The receiver combines a low-noise amplifier with down conversion mixer, a low-pass channel-select filter and a limiter. The various blocks parameters of the receiver like noise figure, gain and IIP3 are simulated and optimized to meet receiver specifications. The receiver simulations show 51.1 dB conversion gain, -7 dBm IIP3, -15 dB return loss (S11) and 10 dB NF
