Use of Complex Valued Least-Squares Solver Techniques for Adaptor S-Parameter and 3-Port Source Match Determination

Least-square solver techniques have been evaluated for use in the accurate determination of the S-parameters of non-insertable 2-port devices and the effective source match of 3-port devices in the frequency range 10 MHz to 50 GHz. The results obtained compare favourably with those made using other methods
