Abstract

Systems and methods for direct load impedance computation for a two-port network are disclosed. For a two-port network connected between a first port and a second port, a method can include defining an equivalent PI network including a first equivalent network element in communication with the first port, a second equivalent network element in communication with the second port, and a third equivalent network element connected between the first port and the second port. A linear passive load can be connected to the second port of the two-port network, currents through the linear passive load, the second equivalent network element, and the third equivalent network element can be measured, and a load impedance of the linear passive load can be determined based on predetermined values of a voltage at the first port and a voltage at the second port.

First claim

What is claimed is:

1. A method for direct load impedance determination for a two-port network comprising:
connecting the two-port network between a first port and a second port;
determining component values for an equivalent PI network that models a linear two-port response of the two-port network, the equivalent PI network comprising a first equivalent network element in communication with the first port and having a first admittance to ground, a second equivalent network elem…
