Product Details
●The HMC7911 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 17 GHz to 20 GHz. This device provides a small signal conversion gain of 18 dB with 30 dBc of sideband rejection. The HMC7911 uses a variable gain amplifier preceded by an in-phase/quadrature (I/Q) mixer that is driven by an active 2× local oscillator (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 HMC7911 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.
