摘    要: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.

关 键 词:甚高频单边带  一次变频  双锁相环电路

Abstract:Nowadays,single side frequency range of short wave band is very crowded.In order to further broaden the utilization of the frequency range of VHF,the research on the VHF SSB mobile receiver is carried out.This paper focuses on the three major technical obstacles encountered in the process of designing the VHF SSB mobile receiver and presents a design program using one time frequency converting,dual-PLL.All the performances of the prototype receiver are acquired.This design is of some reference value when li...
Keywords:SSB of VHF  one time frequency converting  dual-PLL circuit
