General Description

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.

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.

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.
