A Harmonic-Balance-oriented modeling approach for microwave electron devices

A technology-independent model of microwave electron devices, the Nonlinear Integral Model, is proposed. This model is rigorously derived from the Volterra series under mild assumptions valid for most types of electron devices and is particularly suitable for circuit analysis based on harmonic-balance techniques. Moreover, it makes it possible to compute the large-signal response of an electron device directly in terms of data obtained by physics-based numerical simulations. The validity of the model is confirmed both by simulation and by experimental results
