F-band Low-loss Tapered Slot Transition for Millimeter-wave System Packaging

  • 1. Chalmers University of Technology


This work presents a packaging solution at F-band (90 - 140 GHz) using on-chip waveguide transition. The transition is realized using a Linearly Tapered Slot (LTS) implemented in a commercial Gallium Arsenide (GaAs) Monolithic Microwave Integrated Circuit (MMIC) technology. The LTS is mounted in the E-plane of a split-block waveguide module and fed through a microstrip line. The transition is experimentally verified using a back-to-back test structure and it exhibits an average insertion loss of 1.7 dB over the frequency range extending from 100 to 135 GHz. This work presents an on-chip packaging technique to realize the interface between MMICs and standard waveguides at millimeter-wave (mmW) frequencies and hence addressing one of the main integration challenging facing systems operating at that range.
