General Description

The MAX9986 high-linearity downconversion mixer pro-

vides 10dB gain, +23.6dBm IIP3, and 9.3dB NF for

815MHz to 995MHz base-station receiver applications.

With a 960MHz to 1180MHz LO frequency range, this

particular mixer is ideal for high-side LO injection

receiver architectures. Low-side LO injection is sup-

ported by the MAX9984, which is pin-for-pin and func-

tionally compatible with the MAX9986.

In addition to offering excellent linearity and noise perfor-

mance, the MAX9986 also yields a high level of compo-

nent integration. This device includes a double-balanced

passive mixer core, an IF amplifier, a dual-input LO selec-

table switch, and an LO buffer. On-chip baluns are also

integrated to allow for single-ended RF and LO inputs.

The MAX9986 requires a nominal LO drive of 0dBm, and

supply current is guaranteed to be below 265mA.

The MAX9984/MAX9986 are pin compatible with the

MAX9994/MAX9996 1700MHz to 2200MHz mixers,

making this entire family of downconverters ideal for

applications where a common PC board layout is used

for both frequency bands. The MAX9986 is also func-

tionally compatible with the MAX9993.

The MAX9986 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.
