设计了水声信号发生系统中的功率放大电路，可将前级电路产生的方波信号转换为正弦信号，同时进行滤波、功率放大，使其满足换能器对输入信号的要求。该电路以单片机AT89C52，集成6阶巴特沃思低通滤波芯片MF6以及大功率运算放大器LM12为核心，通过标准RS232接口与PC进行通信，实现信号增益的程控调节，对干扰信号具有良好的抑制作用。经调试该电路工作稳定正常，输出波形无失真，在输出功率以及放大增益、波纹系数等方面均满足设计要求。 This paper presented a design and implementation of underwater acoustic power amplifer. This circuit converted the rectangle signal generated by frontend circuit into the sine signal， then filtered and power amplification， it meets the requirements of the transducer.Included AT89C52， 6th order Butterworth filter MF6， hipower amplififier LM12.Communication with PC through the RS232 port. The signal gain is adjustable and could be remote controlled. It has a good inhibitory effect on the interference signal. After debugged， this circuit works stable， the output waveform has no distortion， it meets the design requirement in outprt power， amplifier gain and ripple factor.

This book is concerned with integrated circuits and systems for wireless and mobile communications. Circuit techniques and implementation of reconfigurable low-voltage and low-power single-chip CMOS transceivers for multiband and multi- mode universal wireless communications are the focus of the book. Applications encompass both long-range mobile cellular communications (GSM and UMTS) and short-range wireless LANs (IEEE802.11 and Bluetooth). Recent advances in research into transceiver architecture, RF frontend, analogue baseband, RF CAD and automatic testing are reported.
