K-band Quadrature Mixers with Plastic-packaged Diodes Matjaz Vidmar University of Ljubljana, Slovenia Quadrature mixers (also known as IQ mixers) are important signal-processing components in radio transmitters (as vector modulators) and radio receivers (as image-reject mixers and/or demodulators) as well as other microwave equipment (phase-locked loops (PLL)). A quadrature mixer...

A 76 to 77 GHz GMIC Mixer for Automotive Radar A 76 to 77 GHz mixer that uses flipped Hewlett-Packard HSCH-9401 Schottky diodes has been developed on a 127-µm-thick glass microwave integrated circuit (GMIC) for autonomous cruise control (ACC) radar applications. The design process for diode modeling and mixer...
