This paper presents the implementation of a data acquisition system, where the folded thermal noise is reduced by using two consecutive subsampling processes. The presented implementation is used to test wideband multistandard receivers covering most of present communication standards. The proposed system converts a 20-MHz signal modulated with a programmable carrier frequency up to 6.5 GHz, so that it could be used as a universal receiver for software-defined radio applications. Experimental results show an effective number of bits larger than 9 bits up to 2.9 GHz, 8 bits up to 6.5 GHz, and 6.4 bits up to 20 GHz of input carrier frequency.
