MAX2042A

SiGe High-Linearity, 1600MHz to 3900MHz

Upconversion/Downconversion Mixer with LO Buffer

General Description

The MAX2042A single, high-linearity upconversion/

downconversion mixer provides up to +33dBm input

IP3, 7.25dB noise figure, and 7.2dB conversion loss for

1600MHz to 3900MHz GSM/EDGE, CDMA, TD-SCDMA,

WCDMA, LTE, TD-LTE, WiMAXK, and MMDS wireless

infrastructure applications. With an ultra-wide 1300MHz

to 4000MHz LO frequency range, the IC can be used in

either low-side or high-side LO injection architectures for

virtually all 1.7GHz to 3.5GHz applications (for a 2.5GHz

variant tuned specifically for low-side LO injection, refer

to the MAX2042).

In addition to offering excellent linearity and noise

performance, the IC 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

IC requires a nominal LO drive of 0dBm, and supply

current is typically 140mA at VCC = 5.0V or 122mA at

VCC = 3.3V.

The MAX2042A is pin compatible with the MAX2042

2000MHz to 3000MHz mixer. The MAX2042A is also pin

similar with the MAX2029/MAX2031/MAX2033 650MHz

to 1550MHz mixers, the MAX2039/MAX2041 1700MHz

to 3000MHz mixers, and the MAX2044 2300MHz to

4000MHz mixer, making the entire family of upconverters/

downconverters ideal for applications where a common

PCB layout is used for multiple frequency bands.

The MAX2042A is available in a compact, 20-pin TQFN

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

performance is guaranteed over the extended TC = -40NC

to +85NC temperature range.
