Abstract:In this letter, we report on a high‐performance 94‐GHz millimeter‐wave monolithic integrated circuit (MMIC) mixer module using 0.1‐μm metamorphic high electron mobility transistors. A modified resistive mixer with a RF amplifier was proposed in this work for low conversion loss and high LO‐RF isolation. The MMIC mixer module was fabricated using a MMIC chip and CPW‐waveguide transitions. The fabricated mixer chip and module showed a low conversion loss of 6.3 and 9.5 dB, and LO‐RF isolations of 24.8 and 30.4 d… Show more
