Design and Implementation of Front-end Circuit in the 250MHZ SSB Receiver

In order to effectively curb various kinds of interference and improve the performance of VHF single sideband(SSB) receiver, a good front-end circuit is quite important. On this issue, the paper describes the role of front-end circuit in VHF-SSB receiver and the design of front-end circuit in 250MHZ SSB receiver, and gives the experimental results. The results show that various kinds of interference have been effectively curbed.
