Abstract
The measurement of impedance above 110 GHz lacks both commercially available measurement equipment and good standard impedances. This paper discusses these problems and goes onto suggest some ways forward for solving them. The paper includes a description of some on-wafer measurements of impedances at 140 GHz and concludes with some recommendations for future research.
