MICRF005无线收发器的原理和应用

Principle and Application of the UHF Transceiver MICRF005

MICRF005芯片是Micrel公司生产的一种高速无线UHF收发器,是一款单芯片OOK收发器 ,可用于远距离低功率无线设备中单向和双向无线连接。MICRF005采用“天线输入 ,数据输出”工作方式 ,所有RF和IF调谐均可在集成电路内自动完成 ,因此具有很高的可靠性和极低的功耗。文中介绍了MICRF005的主要特点、结构原理和引脚功能 。

The MICRF005QwikRadio TM UHF transceiver is a single-chip OOK(on-off keyed)transceiver IC for remote wireless applications.This device is a true single-chip,”antenna-in,data-out”device.All RF and IF tuning are accomplished automatically within the IC,which eliminate manual tuning production costs and results in a highly reliable,extremely low-cost solution for high-volume wireless applications.
