SiGe High-Linearity, 2000MHz to 3000MHz

Upconversion/Downconversion Mixer with LO Buffer

General Description

The MAX2042 single, high-linearity upconversion/down-

conversion mixer provides +36dBm IIP3, 7.3dB noise fig-

ure, and 7.2dB conversion loss for 2000MHz to 3000MHz

WCS, LTE, WiMAXK, and MMDS wireless infrastructure

applications. With a wide LO frequency range of 1800MHz

to 2800MHz, this particular mixer is ideal for low-side LO

injection receiver and transmitter architectures. High-side

LO injection is supported by the MAX2042A, which is pin-

pin and functionally compatible with the MAX2042.

In addition to offering excellent linearity and noise

performance, the MAX2042 also yields a high level of

component integration. This device includes a double-

balanced passive mixer core, an LO buffer, and on-chip

baluns that allow for single-ended RF and LO inputs.

The MAX2042 requires a nominal LO drive of 0dBm,

The MAX2042 is pin compatible with the MAX2042A

2000MHz to 3900MHz mixer. The device is also pin simi-

lar with the MAX2029/MAX2031 650MHz to 1000MHz

mixers, the MAX2039/MAX2041 1700MHz to 3000MHz

mixers, and the MAX2044/MAX2044A 3000MHz to

4000MHz mixers, making this entire family of up/down-

converters ideal for applications where a common PCB

layout is used for multiple frequency bands.

The MAX2042 is available in a compact 20-pin thin QFN

(5mm x 5mm) package with an exposed pad. Electrical

performance is guaranteed over the extended -40NC to

+85NC temperature range.
