Abstract: A receiver system using commercially available super high-speed data converters that are able to directly digitize at multiple GHz sampling rates with sufficient accuracy to fit many radio applications. Unlike conventional receivers, no down converters or mixing stages are required. Instead it uses a bank of RF filters from which the desired RF filter, based on the frequency band of interest, is switched in. The frequency spectrum scan rate is very fast as the settling time for the simple RF front-end is small and the speed of RF switching is high. The filtered output is digitized at a multiple GHz sampling rate and all signal processing is done by FPGA or a combination of FPGA and/or a general-purpose processor.
