General Description

The Helical Duplexer is a different frequency dual -worker radio station. The main accessories of the relay platform are to separate the launch from the receiving signal to ensure that the receiving and transmission can work normally at the same time. Composition to avoid transmission of the transmitting signal of this machine to the receiver. Generally, the dual device is composed of six block filters (trap), and each resonance is in the transmission and receiving frequency. Receive end filter resonance at the transmitting frequency, and prevent finger transmitting power string into the receiver, the transmission end filter resonance in the receiving frequency.

Topwave model TPW-DP-3852-NF, it is a UHF 380-520MHz duplexer with N female connectors, this duplexer mainly used in relay platform and wireless intercom system.
