QuinStar Technology supplies series QMI mixer with I (in phase) and Q(quadrature phase) outputs. They are offered over the RF range of 18 to 110 GHz. These mixers utilize two balanced mixers, a 90 degree RF hybrid and an LO power splitter integrated to achieveexcellent amplitude and phase balanced I_Q outputs. Using an external IF quadrature hybrid combiner, these mixers can be configured as image reject mixers or as single-sideband upconverters. Good LO to RF isolation is achieved over a relatively broad RF and LO frequency ranges. Typical IF range is from DC to 3 GHz. Models with subharmonic LO(local oscillator at one-halfthe RF frequency) can also be provided as custom products. The mechanical design of these mixers is very compact and can be customized to suit any specific application and outline requirement. Both waveguide and coaxial interfaces are offered as options for RF and LO ports.These IQ mixers find applications in communication equipment,radar sensors, EW/ECM subsystems and instrumentation receivers.
