Abstract :
A new generalized FOURIER transform method, which is both accurate and fast for analysing almost periodic steady-state responses of microwave nonlinear circuits, is used to simulated the 3rd-order intermodulation of a GaAs MESFET amplifier. The simulated and measured results quite agree with each other, and the relation between intermodulation and embedding impedances of harmonic components is also investigated.
