6 cavity duplexer 138-156 MHz N female
Description
The 6-cavity duplexer for the 160 MHz band is a duplex radiotelephone solution designed for installations requiring operation in the 138 - 156 MHz frequency range. In the selected version, it offers a duplex spacing of 8 - 10 MHz and is primarily suitable for equipment with Tx and Rx on single frequencies; it can also be used on multiple channels with a defined port band, with slightly reduced performance and factory calibration recommended.
Amphenol-Procom uses high-Q, temperature-compensated helical resonators to keep the physical dimensions of the filter small. Construction includes extruded aluminum enclosure, passivated steel frame, Teflon insulation in the hard coaxial cables and connectors, and a black vinyl jacket to help prevent corrosion.
