SiGe High-Linearity, 1700MHz to 2200MHz
Downconversion Mixer with LO Buffer/Switch
General Description
The MAX9996 high-linearity downconversion mixer pro-
vides 8.3dB gain, +26.5dBm IIP3, and 9.7dB NF for
1700MHz to 2200MHz UMTS/WCDMA, DCS, and PCS
base-station receiver applications. With a 1900MHz to
2400MHz LO frequency range, this particular mixer is
ideal for high-side LO injection receiver architectures.
Low-side LO injection is supported by the MAX9994,
which is pin-for-pin and functionally compatible with the
MAX9996.
In addition to offering excellent linearity and noise per-
formance, the MAX9996 also yields a high level of com-
ponent integration. This device includes a double-
balanced passive mixer core, an IF amplifier, a dual-
input LO selectable switch, and an LO buffer. On-chip
baluns are also integrated to allow for single-ended RF
and LO inputs. The MAX9996 requires a nominal LO
drive of 0dBm, and supply current is guaranteed to be
below 240mA.
The MAX9994/MAX9996 are pin compatible with the
MAX9984/MAX9986 815MHz to 995MHz mixers, mak-
ing this entire family of downconverters ideal for appli-
cations where a common PC board layout is used for
both frequency bands. The MAX9996 is also functional-
ly compatible with the MAX9993.
The MAX9996 is available in a compact, 20-pin, thin
QFN package (5mm x 5mm) with an exposed paddle.
Electrical performance is guaranteed over the extended
-40°C to +85°C temperature range.
