Characterization of Interconnects on Multilayer High Frequency PCB for D- Band

The paper presents the characterization of interconnects for D-band on multilayer high frequency PCBs. The losses demonstrated at 150 GHz for a microstrip line, a coplanar waveguide and a single flip-chip transition are 1.9 dB/cm, 1.8 dB/cm and 0.3 dB (for 60 μm bumps), respectively. The applicability of multilayer high frequency PCB technology as a low cost integration platform for D-band is proven.
