Mobile Band Reject Duplexers • Coaxial Type • 340-960 MHz

Product features
* Coaxial mobile duplexers intended to be used in systems up to 50 watts in the 340 – 960 MHz range.
* Resonant cavities are interconnected in a band reject configuration, which allows typical Tx to Rx frequency separation of 5.0 MHz in the range of 340-520 MHz, and 9.0 MHz in the range of 800 – 960 MHz.
* Semi-rigid coaxial cables are used to improve Tx to Rx isolation.
* Six TEM silver plater cooper resonators, housed in 6063-T6 alodine finished aluminium cavities.
* Standard connectors are BNC female.

Compact Base Station Duplexers • 136-512 MHz

Product features
* Compact Base Station duplexers, designed for applications where high power and small space is a complicated trade-off.
* Six high Q (helical or coaxial) resonant cavities, interconnected in a band pass – band reject configuration which allows a small Tx-Rx separation.
* Design and rugged construction that ensures to the units long term and thermal stability.
* Supplied with brackets for installation on a chassis.
* Standard connectors are N female.

Band Pass-Band Reject Base Station Duplexers • 136-960 MHz

Product features
* Duplexers intended to be used in high power applications, or when there is small Tx-Rx separation.
* Around the pass frequencies, these duplexers display a quasi band pass response, providing an additional selectivity that protects the receiver against interferences and reduces the noise and spurious emission of the transmitter.
* Good thermal stability is obtained by a fine design an by the use of INVAR rods to control the tuning of each resonator.
* Supplied with mounting brackets for 19″ racks.
* Standard connectors are N female.
