SiGe High-Linearity, 815MHz to 1000MHz
Downconversion Mixer with LO Buffer/Switch
General Description
The MAX9986A high-linearity downconversion mixer
provides 8.2dB gain, +25dBm IIP3, and 10dB NF for
815MHz to 1000MHz base-station receiver applica-
tions. 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 MAX9986A.
In addition to offering excellent linearity and noise perfor-
mance, the MAX9986A 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 MAX9986A requires a nominal LO drive of 0dBm,
and supply current is guaranteed to be below 250mA.
The MAX9986A is a derivative version of the MAX9986
with improved large-signal blocking performance. The
MAX9984/MAX9986/MAX9986A are pin compatible with
the MAX9994/MAX9996 1700MHz to 3000MHz mixers,
making this entire family of downconverters ideal for
applications where a common PC board layout is used
for both frequency bands. The MAX9986A is also func-
tionally compatible with the MAX9993.
The MAX9986A 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.
