CA 2218861
A method and system for reducing spurious signal content in transmitters is described. A lowpass or bandpass filter can be inserted after an input signal node of a transmitter to remove interfering signals generated, for example, from another input signal node of the transmitter. In this way integration of the transmitter circuitry is enhanced.
L'invention concerne un procédé et un système permettant de réduire la teneur en signaux parasites dans des émetteurs. On insère à cet effet, un filtre passe-bas ou passe-bande en aval d'un noeud de signaux d'entrée d'un émetteur afin d'éliminer les signaux d'interférence produits par exemple à partir d'un autre noeud de signaux d'entrée de l'émetteur. Ceci permet d'augmenter l'intégration des circuits de l'émetteur.
