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 utilises 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. LO/RF isolation is > 30 dB with IF frequency range of DC to 7 GHz.
