Description
Max9984 Sige High-linearity, 400mhz To 1000mhz Downconversion Mixer With Lo Buffer/switch
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX9984 high-linearity downconversion mixer pro-
vides 8.1dB gain, +25dBm IIP3, and 9.3dB NF for
400MHz to 1000MHz base-station receiver applica-
tions*. With an optimized 570MHz to 850MHz LO fre-
quency range, this particular mixer is ideal for low-side
LO injection receiver architectures in the cellular band.
High-side LO injection is supported by the MAX9986,
which is pin-for-pin and functionally compatible with the
MAX9984.
In addition to offering excellent linearity and noise perfor-
mance, the MAX9984 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 MAX9984 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 MAX9984 is also func-
tionally compatible with the MAX9993.
The MAX9984 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.
