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.
