Active Interferometry-Based Vector Network Analyzer Reference Impedance Renormalization

An active interferometry-based measurement configuration for the reference impedance renormalization of a vector network analyzer is presented. The method can be implemented using only a 2-source vector network analyzer, reducing the set-up complexity required. High-impedance surface mount resistors are used to demonstrate the impedance renormalization by minimizing their high reflection. In addition, the method is implemented using the network analyzer's software.
