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.
