The RFMS-4X256-B from Corry Micronics is a 4 x 256 Switch Matrix that operates from 0.9 to 2.5 GHz. It allows 4 RF common ports to be routed to any of 256 RF Ports. The switching system has a compression point of 30 dBm, return loss under -8 dB and an isolation of 80 dB. This is a blocking matrix, which means 2 common ports cannot be connected to the same output port simultaneously. Switching can be manually set via a the display on the front panel or over Ethernet or USB ports using a TCP/IP protocol provided with the unit. This Matrix can also be programmed to execute a sequence of up to 64,000 switching operations. It can be switched at over 200,000 cycles per second.
