Abstract
A frequency transposition device including an input terminal for receiving an incident signal SI and a modulator of the one-bit delta-sigma type MDU connected to the input terminal. A generator MGN provides a periodic auxiliary signal SAX with a frequency equal to a desired transposition frequency. A frequency transposer of the Gilbert cell type has a signal input BES connected to the output of the generator, a control input BCO connected to the output of the delta-sigma modulator MDU, and an output BS delivering a transposed signal STR.
