This paper describes the development and fabrication of two 600 GHz resistive sub-harmonic down conversion mixer submillimeter-wave integrated circuits (S-MMICs), formed by a combination of a frequency multiplier by- six sub-circuit and a fundamental mixer sub-circuit. The mixer circuits were designed in a grounded coplanar waveguide transmission line technology (GCPW) with 14 µm and 7 µm ground-to-ground-spacing. Both versions were fabricated in a 35 nm metamorphic high electron mobility transistor (mHEMT) technology. With a 2 dBm W-band local oscillator (LO) signal the best mixer S-MMIC achieves a maximum conversion gain of -9.2 dB together with an operation frequency range of 76 GHz from 530 to 606 GHz.
