A method and system for de-embedding an on-wafer device is disclosed. The method comprises representing the intrinsic characteristics of a test structure using a set of ABCD matrix components; determining the intrinsic characteristics arising from the test structure; and using the determined intrinsic characteristics of the test structure to produce a set of parameters representative of the intrinsic characteristics of a device-under-test (“DUT”).

A semiconductor device for transmitting a radio frequency signal along a signal line includes a signal line that extends along a principal axis. On one side of the signal line is a first dielectric, and on the opposite side of the signal line is a second dielectric. First and second ground lines are proximate to the first and second dielectrics, respectively, and the ground lines are approximately parallel to the signal line. The device has a transverse cross-section that varies along the principal axis.
