Claim One:
1. A computer-implemented method for use with modeling a passive multiplexer, the method comprising: obtaining parameters for individual signal filters of a plurality of signal filters of the passive multiplexer, the plurality of signal filters joined at a common junction; calculating an initial resonant frequency offset vector estimation, where the calculating is: performed through iterative reduction for iterative combinations of resonant circuits connected at the common junction and appropriately terminated, performed at a normalized frequency offset for the iterative combinations, and based on the filter parameters of the iterative combinations; calculating an initial match frequency vector based on the parameters such that the input reflection coefficient vector substantially equals zero; calculating an initial input impedance vector from the initial match frequency vector, the calculating an initial input impedance vector based on: an initial resonant frequency offset vector estimation at the common junction, and the parameters; iteratively recalculating an updated input impedance vector for an updated match frequency vector, where: the updated match frequency vector is based on updated resonant frequency offset vectors, and the updated resonant frequency offset vectors are based on a difference between a present input impedance vector and an ideal input impedance vector while the input reflection coefficient vector for the multiplexer substantially equals zero; and converging on a set of multiplexer parameters for the passive multiplexer using the iteratively recalculating.
