Features 1、Stable Structure: Simple design makes it easy to install, effectively improve the signal of wireless communication in large areas, such as residential areas, shopping malls, hotels, and more. 2、6 Cavity Design: Each resonant can transmits and receives frequency. The receiving end filter resonates at the transmitting frequency and prevents the transmitting power string into the receiver. The transmitter filter resonates at the receiving frequenc 3、High and Low disjoint frequency bands: the signals on Low and High frequency band can coexist on one port without interfering with each other. 4、25W RF Power Handling: Beneficial to improve the output power of the whole machine, improve the efficiency, and reduce the calorific power. 5、The isolation of this duplexer is more than 75dB, which ensures high sensitivity in signal receiving and transmitting. Specification Description: This duplexer is a passive device that allows multiplexing frequency in radar and radio communications systems. It isolates the receiver from the transmitter while permitting them to share a common antenna, so that to ensure both receiving and transferring can work properly at the same time.
