What is a TX RX Multicoupler?

TX RX Multicoupler is a device used to couple the transmitter and receiver to an antenna. It transmit signals with high port-to-port isolation. A typical multicoupler consists of filters/duplexers, a Low Noise Amplifier and a power divider. It is an important part of a telecommunication system.

When multiple receivers or transmitters or radio stations share an antenna, in order to avoid mutual interference between the devices, a coupling device is used between the antenna and each device.

Since the multi-channel coupler can enable multiple transceiver devices to share an antenna at the same time, it can greatly reduce the number of antennas in the system, reduce the cost of communication equipment, and provide electromagnetic compatibility performance of the communication system, and has been widely used in wireless communications.

The application scenarios of wireless communication cover satellite communications, telecommunications, radio and television, radio monitoring, weather radar, civil aviation radar, defense, automated testing of components, etc.

Comparison of TX/RX Multicoupler, TX combiner, RX Splitter

TX/RX Multicoupler: a combination of TX combiner and RX splitter.

TX Combineror TX same band combiner, it is a passive structure used to combine transmitters to one antenna. It provides custom band as per request and provides high isolation port to port. The device is commonly in 2-CH, 4-CH, 60CH or 8-CH optional with 1U high compact housing for convenient installing.

RX Splitter: it is a structure used to connect receivers to a single antenna.
