Spatial Power Combining and Impedance Matching Silicon IC-to-Waveguide Contactless Transition

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review


In this paper a new multi-step joint-design approach is described for a multi-channel power amplifier integrated with an IC-to-Waveguide transition. The approach enables an optimal impedance match of a waveguide to an integrated-circuit via a contactless transition. Spatial power combining with a non-isolated contactless transition is achieved in the input and output networks of the power amplifier. Simulation results are presented which are in agreement with the joint-design requirements. This methodology enables IC-to-Waveguide integration and provides a suitable approach for mm-wave system integration.
