MAX2031ETP+
High-Linearity, 650MHz to 1000MHz Upconversion/Downconversion Mixer with LO Buffer/Switch
General Description
The MAX2031 high-linearity passive upconverter or
downconverter mixer is designed to provide +36dBm
IIP3, 7dB NF, and 7dB conversion loss for a 650MHz to
1000MHz RF frequency range to support GSM/cellular
base-station transmitter or receiver applications. With a
650MHz to 1250MHz LO frequency range, this particu-
lar mixer is ideal for high-side LO injection architec-
tures. For a pin-to-pin-compatible mixer meant for
low-side LO injection, refer to the MAX2029.
In addition to offering excellent linearity and noise per-
formance, the MAX2031 also yields a high level of com-
ponent integration. This device includes a double-
balanced passive mixer core, a dual-input LO selec-
table switch, and an LO buffer. On-chip baluns are also
integrated to allow for a single-ended RF input for
downconversion (or RF output for upconversion), and
single-ended LO inputs. The MAX2031 requires a nomi-
nal LO drive of 0dBm, and supply current is guaranteed
to be below 100mA.
The MAX2031 is pin compatible with the MAX2039/
MAX2041 1700MHz to 2200MHz mixers, making this
family of passive upconverters and downconverters
ideal for applications where a common PC board layout
is used for both frequency bands.
The MAX2031 is available in a compact 20-pin thin
QFN package (5mm x 5mm) with an exposed pad.
Electrical performance is guaranteed over the extended
-40°C to +85°C temperature range.

Note 1:Maximum, reliable, continuous input power applied to the RF and IF port of this device is +12dBm from a 50Ωsource.
Note 2:Based on junction temperature TJ= TC+ (θJCx VCCx ICC). This formula can be used when the temperature of the exposed
pad is known while the device is soldered down to a PCB. See the Applications Informationsection for details. The junction
temperature must not exceed +150°C.
Note 3:Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to /thermal-tutorial.
Note 4:Junction temperature TJ= TA+ (θJAx VCCx ICC). This formula can be used when the ambient temperature of the PCB is
known. The junction temperature must not exceed +150°C.
Note 5:TCis the temperature on the exposed pad of the package. TAis the ambient temperature of the device and PCB.
