Abstract :
The noise performance of autonomous nonlinear subsystems including mixer/LO subassemblies is computed by a perturbative analysis of the quasi-periodic regime generated by the intermodulation of the RF signal with the autonomous local oscillation. It is shown that classical analyses based on the perturbation of the time-periodic LO regime fail to correctly describe the LO contribution to the IF noise.<>
