設計了水聲信號發(fā)生系統(tǒng)中的功率放大電路，可將前級電路產(chǎn)生的方波信號轉(zhuǎn)換為正弦信號，同時進行濾波、功率放大，使其滿足換能器對輸入信號的要求。該電路以單片機AT89C52，集成6階巴特沃思低通濾波芯片MF6以及大功率運算放大器LM12為核心，通過標準RS232接口與PC進行通信，實現(xiàn)信號增益的程控調(diào)節(jié)，對干擾信號具有良好的抑制作用。經(jīng)調(diào)試該電路工作穩(wěn)定正常，輸出波形無失真，在輸出功率以及放大增益、波紋系數(shù)等方面均滿足設計要求。 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.
