A new sampled data technique is introduced, capable of providing real-time spectral compression of large input bandwidths, while requiring a single sampling operation to be performed at the lower output data rate. The proposed configuration, based on a tapped delay line and CMOS integrated multiplexers, exhibits dual properties for spectral expansion; unique features are the capability of accepting data directly at RF format, with power consumption and switching speed requirements independent of the maximum processed data rate. Sampling rates as high as 25 MHz are demonstrated, requiring only 2.5 MHz tap switching frequency to be performed for a time compression factor of 10.
