High-Linearity, 815MHz 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 an 815MHz
to 1000MHz RF frequency range to support GSM/cellu-
lar base-station transmitter or receiver applications.
With a 960MHz to 1180MHz LO frequency range, this
particular mixer is ideal for high-side LO injection archi-
tectures. For a pin-to-pin-compatible mixer meant for
low-side LO injection, contact the factory.
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 paddle.
Electrical performance is guaranteed over the extended
-40°C to +85°C temperature range.

*Maximum reliable continuous input power applied to the RF and IF port of this device is +12dBm from a 50source.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
