Abstract :
In this paper, a 340GHz GaAs monolithic integrated sub-harmonic mixer based on planar Schottky diode is presented. The mixer circuit is fabricated on a 12um GaAs substrate included planar Schottky diode in a balanced configuration, the passive RF/LO and IF matching networks, filtering circuits, as well as transitions from waveguide to suspended micro-strip. Simulated results for the 340 GHz mixer achieved DSB conversion loss of 6.49dB at 306.4GHz when the LO pumped power was 5.96dBm at 165GHz. The conversion loss was less than 8dB from 290GHz to 355GHz.
