HMC7912 21 GHz to 24 GHz, GaAs, MMIC, I/Q Upconverter
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.
