The HMC7912 is a compact, gallium arsenide (GaAs), pseudomorphic (pHEMT), monolithic microwave integrated circuit (MMIC) upconverter in a RoHS compliant, low stress, injection molded plastic LFCSP package that operates from 21 GHz to 24 GHz. This device provides a small signal conversion gain of 15 dB with 22 dBc of sideband rejection. The HMC7912 uses a variable gain amplifier preceded by an in-phase/quadrature (I/Q) mixer that is driven by an active 2× LO multiplier. IF1 and IF2 mixer inputs are provided, and an external 90° hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for filtering of the unwanted sideband. The HMC7912 is a much smaller alternative to hybrid style single sideband (SSB) upconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface-mount manufacturing techniques.
