The XRM-90-XX from Comprod are Multi-Channel Receiver Multicouplers that operate from 896 to 960 MHz. They are available in 2, 4, 8, 12, 16, and 32 port configurations and can combine multiple receiver frequencies onto the same antenna. These Multicouplers integrate an amplifier that provides a gain of up to 32 dB with a noise figure of 1.3 dB, and a splitter that offers a port-to-port isolation of more than 23 dB. They require a DC supply from 13 to 28 V and consume 130 mA of current (plug-in power supply option available). These multicouplers are available either in 19-inch rack-mount or cavity-mount enclosures with N-type (BNC optional) connectors.
