摘要：应用CXA1019S芯片完成接收机混频、中放、解调等的设计，并用芯片BU2614以PLL
频率合成的方法产生稳定的本振和控制输入调谐回路的谐振频率，从而实现电调谐。单片机采用
MCS-51系列对频率合成器BU2614进行控制，加上键盘、显示和存储器电路，可实现多种程控搜
索、电台存储等功能。-Abstract: The complete receiver chip CXA1019S mixer, amplifier, demodulator, such as design, and BU2614 chip PLL frequency synthesizer to generate a stable method of vibration and control input of the tuner circuit resonant frequency, in order to achieve electrical tuning. Singlechip using MCS-51 series of the frequency synthesizer BU2614 control, together with the keyboard, display and memory circuits, can achieve a variety of program-controlled search, radio storage functions.
