Abstract

In this study, we designed and fabricated GaAs AP-SBDs for a 300 GHz subharmonic mixer. To enhance the reliability of electromagnetic simulations, we measured and calculated the optical parameters of the material in the terahertz range and designed a component with minimal impedance variation across the frequency range of 140-300 GHz. GaAs AP-SBDs were fabricated using MOCVD and an i-line stepper, followed by electrical characterization. Finally, a subharmonic mixer was constructed using WR3.4/WR6.5 waveguides, achieving an single side band conversion loss of 9.72 dB and a 3 dB bandwidth of 40 GHz.
