Advances in Submillimeter Semiconductor-Based Device Designs and Processes

Abstract

Planar submillimeter circuits are slowly replacing whisker-contacted devices at frequencies above 100 GHz, but in many cases the size constraints brought on by the short wavelengths associated with high frequency operation have not been adequeately addressed. Also, reproducibility becomes more important as we make the transition from tunable, whisker-based circuits to more monolithic designs. We are continuing to develop new circuites with more reproducible characteristics.
