Abstract

The metric of unaccounted power is introduced as a sufficient condition to successful thru‐reflect‐line (TRL) calibrations for microstrip circuits. It is then demonstrated how this metric can be used both a priori, with simulation data, and a posteriori, with measured data, to evaluate the efficacy of coplanar waveguide to microstrip transitions in TRL calibrations. This demonstration is performed with four different transition topologies, two of which utilize coaxial edge mount connectors and two of which utilize ground‐signal‐ground coplanar probes. © 2008 Wiley Periodicals, Inc.

## Abstract This paper presents a method for characterizing coplanar waveguide‐to‐microstrip (CPW‐M) transitions by using on‐wafer coplanar (CPW) microprobes. It is based on extracting the transmission matrix of the CPW‐M transition from the measurement of the __S__ parameters of two microstrip tra
