I&Q and QPSK Modulators / Demodulators

Mini-Circuits offers a wide selection of QPSK modulators and I&Q modulator/demodulators covering RF/LO frequencies from 1 to 2000 MHz and I&Q frequencies from DC to 5 MHz. Available in coaxial connectorized and surface mount packages, these components provide excellent harmonic rejection as well as good carrier and sideband rejection while maintaining low conversion loss over their operating range.
