220 GHz E-Plane Transition from Waveguide to Suspended Stripline Integrated on Industrial Organic Laminate Substrate Technology

In this paper, an assessment up to 220 GHz of industrial organic laminate substrate technology to integrate millimeter-wave (mmW) waveguide to suspended stripline (SSL) transition is proposed. A WR5 waveguide transition has been manufactured and insertion loss (IL) of 1.4 dB @ 140 GHz and 4.2 dB @ 220 GHz has been achieved, competing with standard approach using a quartz substrate solution with III-V technology. This promising performance paves the way of cost effective mmW and sub-THz module manufacturing leveraging high volume manufacturing packaging processes developed for Si based technologies.
