Abstract
A mixer linearisation technique based on difference frequency injection has been proposed and experimentally presented in a system level approach. The system analysis and the effects of amplitude and phase sensitivity on its performance are described. The technique has been demonstrated with an L-band up-conversion double-balanced diode mixer and both simulation and experimental results achieved have shown that this technique can substantially reduce third-order intermodulation distortion.
