Abstract
Wideband waveguide slot-based bi-directional couplers are combined with waveguide load pull tuners for true vector load pull at sub-THz frequencies. Coupling is constant and Directivity is above average up to 170 GHz and can be extended to 330 GHz and are controlled by the shape, size, and configuration of the slots between the main tuner waveguide and the adjacent coupler waveguide. A calibration method allows full characterization of the coupler-tuner assembly.
