Abstract
A frequency translator includes two multipliers which receive one and the same high-frequency signal on first inputs in quadrature with respect to one another, and one and the same low-frequency signal on second inputs also in quadrature with respect to one another. Each multiplier comprises a pair of elements whose capacitance can be varied in a controlled manner, jointly and in opposite senses, connected in parallel. The respective outputs of the two elements of each pair are combined additively, considering their phase opposition, in order to form the outputs of the two multipliers which supply a summer.
