Mavitek MUD series band pass/band reject, 4 cavity duplexers are designed and produced for the 380-470MHz band. They perform simultaneous receive and transmit function into the same antenna with minimum insertion loss and maximum performance. MUD series duplexers are blue enamel painted copper. The connectors are silver plated and PTFE insulated. MUD series are configured as industrial standard 19”/3U rack mount. With high “Q” values they achieve maximum isolation and superior performance with 5MHz Rx/Tx frequency shift. MUD series perform flawlessly under extreme conditions like -30ºC to +60ºC under 250Watts maximum input power. They are the ideal choice for full duplex repeaters and base stations. MUD 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.
