A Novel Design of Preselector for Advanced VHF Receiver Path
摘要
The trend of increasing data transmission traffic over meter radio channels requires the development of receiving paths that would be capable of operating effectively in a non-stationary electromagnetic environment with a lot of both in-band and out-of-band interferers. This paper discusses technical solution of a preselector designed to work as part of promising VHF transceiver modules. An effective design is proposed, discussed and installed in real devices with details. Experimental results are provided with different coefficients employed to improve the system. The results show promising points for VHF transceivers in various applications.
