12.5 GHz to 16.5 GHz GaAs MMIC I/Q Upconverter

The HMC9060 is a compact, gallium arsenide (GaAs), pseudomorphic high electron mobility transistors (pHEMT), monolithic microwave integrated circuit (MMIC) upconverter in a RoHS compliant low stress injection molded plastic LFCSP package that operates from 12.5 GHz to 16.5 GHz. This device provides a small signal conversion gain of 15 dB with 25 dBc of sideband rejection. The HMC9060 uses a radio frequency (RF) amplifier preceded by an in-phase/quadrature (I/Q) mixer, where the local oscillator (LO) is driven by a driver amplifier. 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 HMC9060 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.
