The HMC7912 is a compact, gallium arsenide (GaAs), pseudomorphic(pHEMT), monolithic microwave integrated circuit(MMIC) upconverter in a RoHS compliant, low stress, injectionmolded plastic LFCSP package that operates from 21 GHz to24 GHz. This device provides a small signal conversion gain of15 dB with 22 dBc of sideband rejection. The HMC7912 uses avariable gain amplifier preceded by an in-phase/quadrature (I/Q)mixer that is driven by an active 2? LO multiplier. IF1 and IF2mixer inputs are provided, and an external 90? hybrid is needed toselect the required sideband. The I/Q mixer topology reducesthe need for filtering of the unwanted sideband. The HMC7912is a much smaller alternative to hybrid style single sideband (SSB)upconverter assemblies, and it eliminates the need for wirebonding by allowing the use of surface-mount manufacturingtechniques.Applications Point to point and point to multipoint radios Military radars, electronic warfare (EW), and electronic intelligence (ELINT) Satellite communications Sensors
