Mavitek MVD series band pass/band reject, 6 cavity duplexers are designed and produced for the 136-150MHz band. They perform simultaneous receive and transmit function into the same antenna with minimum insertion loss and maximum performance. MVD series duplexers are blue enamel painted copper. The connectors are silver plated and PTFE insulated. MVD series are configured to be installed in cabinets if needed. With high “Q” values they achieve maximum isolation and superior performance with 500kHz Rx/Tx frequency shift. MVD series perform flawlessly under extreme conditions like -30ºC to +60ºC under 300Watts maximum input power. They are the ideal choice for full duplex repeaters and base stations. MVD series duplexers will be tuned to the frequencies required by the customer and shipped ready for installation. If field retuning is needed, it can be performed flawlessly by the “Invar” tuning rod within the duplexer’s frequency range.
