Abstract
A synthesizer apparatus is provided allowing very high speed switching while keeping phase continuity. It includes a plurality of cells, each with four mixers, a subtractor and an adder for obtaining at the output two in quadrature signals, of jump frequency .-+.n F.sub.r, n being an integer, from in quadrature signals of a basic frequency F.sub.r. These signals are then multiplied in a terminal circuit with two in quadrature signals relative to a carrier frequency Fc then added so as to produce the signal transposed to the frequency F.sub.c .-+.n F.sub.r desired for use.
