General Description

The Helical filter is named because the spiral resonant is used to achieve the parallel resonance circuit in the coupled resonator filter. The main feature of the spiral filter is that the volume is small, the insertion is small, and the relatively narrowing bandwidth can be achieved.

Topwave model TPW-HF-1317-SMAF, it is low frequency range 136-174MHz helical RF Filter with SMA type connectors. The VHF Filter, whose size is small with low insertion loss, mainly used for wireless telecommunication systems like Bi-directional Amplifier, Wireless intercom repeater.
