Kingtone UHF Duplexer is used to combine TX and RX signals into one RF port , or split TX and RX signals from one RF port.
Duplexer is a device that separates the transmitting and receiving signals to ensure that both receiving and transmitting can work normally at the same time. High isolation and low insertion loss design can effectively isolate uplink and downlink signals and avoid mutual interference between uplink and downlink signals. The duplexer is designed with a six-cavity structure, and a total of 12 groups of resonators are used for the uplink and downlink, which meets the maximum 4M bandwidth.
Main Features
◇ High ports isolation, >80dB
◇ Low insertion loss,<1.5dB
◇ 3U cabinet chassis for Standard 19 inch cabinet
