Abstract
This paper focuses on the ongoing development of supraTHz harmonic mixers at Chalmers University of Technology. The planar, single-ended, x8-harmonic mixers based on Schottky-barrier diodes were realised on a 2-µm GaAs substrate with integrated pyramidal horn. In contrast to our previous design with diagonal horn, the new design addresses sensitivity to E-plane misalignment, a factor that previously compromised mixer performance. Availability of THz harmonic frequency converters operating at ambient temperature is a pivotal step towards the realization of high-resolution THz heterodyne receivers.
