Verification Process

According to the simplified circuit partitioning principle, this paper improves the Modified Nodal Analysis(MNA) of wideband Equivalent Circuit Model(ECM). The form of upconversion impedance is transformed from series into parallel. The results show that in the parallel form, the verification process of impedance type has been eliminated and it will not introduce new nodes. At the same time, the amount of computation has been reduced. The maximum relative error of measured data with this model fit is less than 0.693%. The simulation results and ECM test data are consistent with better at 0 to 8GHz frequency range.
