Features & Benefits

• Latching relays ensure cross points remain connected upon loss of power.

• All active components, including RF matrix cards and power supply, are field replaceable.

• Multiple modules can be combined to create larger matrices.


High Power Latching Relay Blocking Switch

The NEXUS-R is a passive bi-directional blocking matrix switch that can relay 32 A ports to 32 B ports. It is designed to handle high power up to 50W for direct connection to base stations. Based on latching relay switching technology, it retains the connections even upon power loss. Quintech’s proprietary design minimizes the return signal and insertion loss through the switch while maximizing the isolation between ports. Its low loss and distortion preserves signal integrity for performance testing while the high isolation prevents crosstalk between test equipment. As a result, the NEXUS-R has superior RF performance and can be used in highly demanding applications such as base station beam forming testing.
