Demonstrating Broadside-Coupled Coplanar Waveguide Interconnects to 325 GHz

We demonstrate three different broadside-coupled coplanar waveguides (CPWs) to 325 GHz that do not require bump bonds, wire bonds, or direct metal-to-metal bonding. Our design approach used a multimoded distributed theory rather than the conventional <inline-formula> <tex-math notation=&quo...

Summary:We demonstrate three different broadside-coupled coplanar waveguides (CPWs) to 325 GHz that do not require bump bonds, wire bonds, or direct metal-to-metal bonding. Our design approach used a multimoded distributed theory rather than the conventional <inline-formula> <tex-math notation="LaTeX">\lambda/4 </tex-math> </inline-formula> approximation. The different interconnects had insertion losses better than 0.7 dB at 63, 93, and 120 GHz.
