Description

UHF/TETRA Cavity Dual Diplexer 380-386.5/455-460&390-396.5/465-470MHz

UHF/TETRA coaxial cavity duplexer JX-CD4-380M470M-65S is one type of RF passive component designed & produced for sale by Jingxin, which specially features with low insertion loss less than 2.2dB in small volume, measured LxWxH: 276mm x 106mm x 76mm.

The frequency of this duplexer covers  PORT 1 （380-386.5MHz &455-460MHz）and PORT 2 （390-396.5MHz &465-470MHz） with Rejection ≥65dB@390-396.5MHz&465-470MHz,≥65dB@380-386.5MHz&455-460MHz, which works under the power of 20W. This duplexer is produced with SMA-Female connectors, but it can be switched to others according to the demand, such kind of duplexer can bear in the field for a long time.

As promised, all the RF passive components from Jingxin have 3 years warranty.
