Title:
INTEGRATED CROSSPOINT SWITCH WITH BAND TRANSLATION
Document Type and Number:
WIPO Patent Application WO2004054128
Kind Code:
A3
Abstract:
Multiple input signal sources in predetermined frequency bands are each applied to block frequency converters. Each block frequency converter frequency converts an input signal to one of a plurality of predetermined frequency bands. A crosspoint switch is configured to route the frequency converted input signals at one of the plurality of predetermined frequency bands to any one of a plurality of available band translation devices. Each of the band translation devices is configured to frequency convert the signal from a first predetermined frequency band to a second predetermined frequency band. Output signals from one or more band translation devices can be combined into a composite signal.
