Downconversion Mixer with LO Buffer/Switch
General Description
The MAX19985A high-linearity, dual-channel, downcon-
version mixer is designed to provide approximately
8.7dB gain, +25.5dBm of IIP3, and 9.0dB of noise fig-
ure for 700MHz to 1000MHz diversity receiver applica-
tions. With an optimized LO frequency range of
900MHz to 1300MHz, this mixer is ideal for high-side
LO injection architectures in the cellular and new
700MHz bands. Low-side LO injection is supported by
the MAX19985, which is pin-pin and functionally com-
patible with the MAX19985A.
In addition to offering excellent linearity and noise per-
formance, the MAX19985A also yields a high level
of component integration. This device includes two
double-balanced passive mixer cores, two LO buffers,
a dual-input LO selectable switch, and a pair of differ-
ential IF output amplifiers. On-chip baluns are also inte-
grated to allow for single-ended RF and LO inputs.
The MAX19985A requires a nominal LO drive of 0dBm
and a typical supply current of 330mA at V
CC
= +5.0V
or 280mA at V
CC
= +3.3V.
The MAX19985/MAX19985A are pin compatible with
the MAX19995/MAX19995A series of 1700MHz to
2200MHz mixers and pin similar with the MAX19997A/
MAX19999 series of 1850MHz to 3800MHz mixers,
making this entire family of downconverters ideal for
applications where a common PCB layout is used
across multiple frequency bands.
The MAX19985A is available in a 6mm x 6mm, 36-pin
thin QFN package with an exposed pad. Electrical per-
formance is guaranteed over the extended temperature
range of T
C
= -40°C to +85°C.
