How to Use the Quadrature Mixer as a Phase Detector and Single Sideband Modulator

A quadrature mixer consists of two balanced mixers where the RF (or LO) ports are connected along with an in-phase power divider; the LO (or RF) ports are connected with a quadrature hybrid. There are two IF ports, "I" for the in-phase component and "Q" for the 90° out-of-phase component. They are available to the … Continue reading How to Use the Quadrature Mixer as a Phase Detector and Single Sideband Modulator

Which Harmonic Mixer Should I Use for My Spectrum Analyzer?

SAGE Millimeter offers harmonic mixers in two product families: SFH and STH. Their purpose is to extend the operation frequency of the spectrum analyzer and/or the frequency counter to millimeter-wave operations. These cover seven waveguide bands spanning across the frequency range of 26.5 to 170 GHz. The SFH series mixers are based on a balanced structure … Continue reading Which Harmonic Mixer Should I Use for My Spectrum Analyzer?
