Qorvo's QPX0004D is a compact I/Q mixer in die form operating over the 24 to 34 GHz bandwidth that can be configured as an image reject mixer, a single sideband upconverter, or a QPSK modulator/demodulator.
The QPX0004D utilizes two double balanced mixer cells and a 90⁰ hybrid on the LO port. An external 90⁰ 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.
