Abstract

A GaAs micromachined uniplanar quasi-optical mixer is presented for the first time. The main block of the circuit is a membrane-supported double folded slot antenna monolithically integrated with a millimeter-wave Schottky diode. The circuit is designed for the 38 GHz frequency range, using coplanar waveguide technology and full-wave electromagnetic simulations, and is fabricated on a large GaAs membrane. The mixer is characterized using the isotropic conversion losses parameter and a value of 16 dB was measured.
