一种低功率SSB收发信机的设计

低功率业余无线电收发信机是业余无线电爱好者们急需的低功率通信设备.本文介绍了一种低功率SSB收发信机的设计方法及其工作原理.该收发信机提供15 m和20 m两个波段,利用芯片MC1596实现SSB信号的产生及检波,利用芯片NE602完成混频,固定中频为9 MHz.该机体积小、重量轻、成本低、性能好,在低功率业务无线电通信领域中,具有较高的实用价值和广阔的应用前景.

Design of a Low Power SSB Transceiver

Low power amateur radio transceiver is in urgent need to radio amateur. This paper introduces a method of designing low power SSB transceiver as well as its work principle. The transceiver uses chip MC1596 to fulfill the modulation and the demodulation of the SSB signal,and uses chip NE602 as frequency mixer,setting 9 MHz as intermediate frequency. In the domain of low power amateur radio communication, the machine presented in the paper provides high utility value and wide application foreground because of its low cost and high quality.
