Abstract

See full text

A broadband fully micromachined transition from rectangular waveguide to cavity-backed coplanar waveguide line for submillimeter-wave and terahertz application is presented. The cavity-backed coplanar waveguide line is a planar transmission line that is designed and optimized for minimum loss while providing 50 Ohm characteristic impedance. This line is shown to provide less than 0.12 dB/mm loss over the entire J-band. The transition from cavity-backed coplanar waveguide to a reduced-height waveguide is realized in three steps to achieve a broadband response with a topology amenable to silicon micromachining. A novel waveguide probe measurement setup is also introduced and utilized to evaluate the performance of the transitions.
