RFMW announced design and sales support for a commercial off the shelf (COTS) mixer from  Qorvo. The QPX0004D, 24 to 34 GHz I/Q Mixer can be configured as an image reject mixer, a single sideband upconverter, or a QPSK modulator/demodulator. Provided as DIE, the device utilizes two double balanced mixer cells and a 90 -degreehybrid on the LO port. An external 90-degree hybrid on the IF port is required to complete the image rejection or sideband suppression. The QPX0004D is a much smaller alternative to higher cost hybrid I/Q mixers and single sideband upconverter assemblies. LO/RF isolation is > 30 dB with IF frequency range of DC to 7 GHz.
