The adjustable frequency wireless receiver consists of the receive part and the Single Chip Micyoco. The low-power narrowband FM receiver chip MC3362 is adopted as the main part in the receive part. And by using the Phase Locked Loop frequency synthesizing technology,the frequency of the carrier-wave will be locked by the receiver. With the integration chip LM386 chosen in the demodulated signal amplifier, the voltage amplifying multiple was 200. And the AT89C51 chips was used in the Single Chip Micyoco control part to set at the number to MC145151 N0-N8 to make the frequency adjustable. DM162 LCD was adopted in the display part. The C language was used to design the program. Through the test,the whole machine＇s function was very complete, every demand would be realized, the receiving wave was stable, without evident distortion.
