High-Linearity, 1700MHz to 3000MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
General Description
Features
The MAX2041 high-linearity passive upconverter or
downconverter mixer is designed to provide 7.4dB NF
and a 7.2dB conversion loss for an RF frequency range
of 1700MHz to 3000MHz to support UMTS/WCDMA,
DCS, PCS, and WiMAX base-station transmitter or
receiver applications. The IIP3 is typically +33.5dBm
for both downconversion and upconversion operation.
With an LO frequency range of 1900MHz to 3000MHz,
this particular mixer is ideal for high-side LO injection
architectures. (For a pin-compatible mixer meant for
low-side LO injection, refer to the MAX2039.)

In addition to offering excellent linearity and noise perfor-
mance, the MAX2041 also yields a high level of compo-
nent integration. This device includes a double-balanced
passive mixer core, a dual-input LO selectable 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 MAX2041 requires a nominal LO drive of 0dBm, and
supply current is guaranteed to be below 145mA.

ꢀ External Current-Setting Resistor Provides Option
for Operating Mixer in Reduced-Power/Reduced-
Performance Mode
The MAX2041 is pin compatible with the MAX2031
815MHz to 995MHz mixer, making this family of passive
upconverters and downconverters ideal for applications
where a common PC board layout is used for both fre-
quency bands.
ꢀ Lead-Free Package Available
The MAX2041 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.
