GENERAL DESCRIPTION
The ADMV1012 is a compact, gallium arsenide (GaAs) design,
monolithic microwave integrated circuit (MMIC) double sideband
(DSB) downconverter in a RoHS compliant package optimized
for point to point microwave radio designs that operate in the
17.5 GHz to 24 GHz input frequency range.
The I/Q mixer topology reduces the need for filtering of unwanted
sideband. The ADMV1012 is a much smaller alternative to
hybrid style DSB downconverter assemblies and eliminates the
need for wire bonding by allowing the use of surface-mount
manufacturing assemblies.
The ADMV1012 provides 15 dB of conversion gain with 25 dB
of image rejection, and 2.5 dB noise figure. The ADMV1012
uses a radio frequency (RF) low noise amplifier (LNA) followed
by an in phase/quadrature (I/Q), double balanced mixer, where
a driver amplifier drives the local oscillator (LO) with a ×2
multiplier. IF1 and IF2 mixer quadrature outputs are provided,
and an external 90° hybrid is required to select the required
sideband.
The ADMV1012 downconverter comes in a compact, thermally
enhanced, 4.9 mm × 4.9 mm, 32-terminal LCC. The ADMV1012
operates over the −40°C to +85°C temperature range.
