4.7-THz Schottky Diode Harmonic Mixer: Design, Fabrication, and Performance Optimization
Paper in proceeding, 2024
This paper focuses on the ongoing development of supra-THz harmonic mixers at Chalmers University of Technology. The planar, single-ended, x8-harmonic mixers based on Schottky-barrier diodes were realized on a 2-um GaAs substrate with integrated pyramidal horn. In contrast to our previous design with a diagonal horn, the new design addresses sensitivity to E-plane misalignment, which previously compromised mixer performance. The availability of THz harmonic frequency converters operating at ambient temperature is pivotal in realizing high-resolution THz heterodyne receivers.
