The MAX9994 high-linearity downconversion mixer pro-

vides 8.3dB gain, +26.2dBm IIP3, and 9.7dB NF for

1700MHz to 2200MHz UMTS/WCDMA, DCS, and PCS

base-station receiver applications. With a 1400MHz to

2000MHz LO frequency range, this particular mixer is

ideal for low-side LO injection receiver architectures.

High-side LO injection is supported by the MAX9996*,

which is pin-for-pin and functionally compatible with the

MAX9994.

In addition to offering excellent linearity and noise per-

formance, the MAX9994 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 MAX9994 requires a nominal LO

drive of 0dBm, and supply current is guaranteed to be

below 235mA.

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 MAX9994 is also functional-

ly compatible with the MAX9993.

The MAX9994 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.
