Abstract
An accurate model for lossy non-uniform transmission lines is presented. The technique provides a coplanar waveguide (CPW) taper model, which has been used to accurately de-embed measurements of passive CPW components in line geometries differing from the nominal 50Ω geometry of the calibration. The model accounts for both dielectric and conductor losses, and is shown to be in excellent agreement with measured results from 45 MHz to 120 GHz
