目前,短波单边带频段十分拥挤,为了进一步拓宽甚高频频段的利用价值,笔者对甚高频单边带移动接收机进行了研究。文中重点叙述如何解决甚高频单边带移动接收机设计所遇到的三大技术障碍,同时介绍了采用一次变频双锁相环的设计方案,得到了研制出的性能样机的各项指标。该设计方案对于AM、DSB等线性调制接收系统向高频率拓展时有一定的参考价值。 At present, the frequency band of the short-wave single sideband is very crowded. In order to further widen the use value of the very high frequency band, the author studies the VHF sideband mobile receiver. This article focuses on how to solve the three technical obstacles encountered in the design of VHF single sideband mobile receivers, and introduces the design scheme of using a frequency double PLL, and obtains the performance of the prototype developed indicators. The design scheme has certain reference value for AM, DSB and other linear modulation receiving systems to expand to high frequency.
