The SMIQ-1844H+ is a passive wideband in-phase/quadrature (I/Q) mixer fabricated using GaAs HBT technology. The SMIQ1844H+ is usable as a single-sideband upconverter for transmit applications or an image rejection mixer for receiver applications.
The SMIQ-1844H+ is ideal for wideband frequency translation applications that require inherent rejection of image signals and spurious mixing products. The mixer covers a broad band with RF and LO frequency ranges of 18 to 40 GHz and an IF frequency range of DC to 7 GHz. As a passive mixer, the SMIQ-1844H+ offers lower noise figure than active mixers enabling superior dynamic range for high performance applications. The mixer is housed in a compact 4×4 mm 24-Lead QFN-style package, and no DC bias is needed for operation.
