Abstract
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.
