Abstract :
A switch matrix operating with multi-rate digital data streams has been developed and demonstrated. The circuit is to serve as a commutating switch in a multi-band multi-channel receiver. The switch works in space-division mode commutating single-bit multi-rate data streams. A 2 times 2 version of the switch matrix was designed, fabricated at HYPRES 1-kA/cm2, and tested at data rates in excess of 20 GHz. The design and test results will be presented. The final version of the device will be a 3 times 8 switch matrix operating at 40 Gbit/s data rate.
