There is a need for an inexpensive, high-performance, fully-integrable, multi- ~standard transceiver, which suppresses spurious noise signals. The invention provides a topology that satisfies this need, using a first signal generator which produces an oscillator signal f1 and a second signal generator which produces a mono-tonal mixing signal .phi.2, where f1 is a multiple of the frequency of .phi.2; and a logic circuit for generating a multi-tonal mixing signal .phi.1, where .phi.1 * .phi.2 has significant power at the frequency of said local oscillator signal being emulated, neither of said cp1 nor said .phi.2 having significant power at the carrier frequency of said input signal x(t) or said LO signal being emulated.
Selon la présente invention, il s'agit de combler l'absence d'un émetteur-récepteur multinorme entièrement intégrable, hautement performant et peu coûteux qui supprime les signaux de bruit parasite. Cette invention concerne une topologie qui répond à ce besoin et comprend un premier générateur de signaux produisant un signal d'oscillateur f1 et un second générateur de signaux produisant un signal de mélange phi 2 monotonal, f1 étant un multiple de la fréquence de phi 2, ainsi qu'un circuit logique générant un signal de mélange phi 1 monotonal, phi 1* phi 2 présentant une puissance importante à la fréquence de ce signal d'oscillateur local émulé, et aucun de phi 1 ou phi 2 ne présentant une puissance importante à la fréquence porteuse de ce signal d'entrée x(t) ou de ce signal d'oscillateur local (LO) émulé.
