A General-Purpose Program for the Analysis of Nonlinear Microwave Circuits Under Multitone Excitation by Multidimensional Fourier Transform

The paper introduces a user-oriented program providing a general-purpose solution to multitone excitation problems of nonlinear microwave circuits. The use of the harmonic-balance technique coupled to multidimensional Fourier transform eliminates any restriction on the possible combinations of fundamental frequencies and results in a frequency-independent simulation cost. The program offers built-in specialized facilities for the special cases of mixer and intermodulation analysis.
