很多无线应用不需要长距离工作,事实上也不想这么做。它们需要的是极低的功耗,并能容忍很低的数据速率。AMI Semiconductor 公司的AMIS-52100是一种单片收发器,在低于500MHz 的频率下工作。它非常适合于402-405MHz 的可植入医疗器件等场合应用。对于发射器端的调制,这种 IC 使用著名而又简单的幅移键控,接收器路径包括时钟恢复电路和数据 Many wireless applications do not need long-distance work, in fact, do not want to do so. They require very low power consumption and can tolerate very low data rates. AMIS Semiconductor’s AMIS-52100 is a monolithic transceiver that operates at frequencies below 500MHz. It is ideal for applications such as 402-405MHz implantable medical devices. For transmitter-side modulation, this IC uses the well known and simple amplitude shift keying, the receiver path includes clock recovery circuitry and data
