The ZMIQ-143H-S+ is a passive wideband in-phase/quadrature (I/Q) mixer utilizing Mini-Circuits’ own GaAs HBT device, the SMIQ-5143H+. This mixer can be used as a single-sideband upconverter for transmission or as an image rejection mixer for receiving applications. It is particularly well-suited for wideband uses that demand inherent image signal rejection and suppression of undesired sidebands.. The mixer covers a broad band with an RF and LO frequency range of 5 to 14 GHz and an IF frequency range of DC to 3 GHz (operational up to 7 GHz). As a passive mixer, the ZMIQ-143H-S+ offers a lower noise figure than active mixers, enabling superior dynamic range for high performance applications. The mixer is housed in a compact, rugged package with SMA coaxial connections. This model also serves as an excellent evaluation module for the SMIQ-5143H+.
