MAX2032

High-Linearity, 650MHz to 1000MHz Upconversion/Downconversion Mixer with LO Buffer/Switch

Maxim Integrated 

19-4965; Rev 0; 9/09

EVAALVUAAILTAIOBNLEKIT

High-Linearity, 650MHz to 1000MHz Upconversion/

Downconversion Mixer with LO Buffer/Switch

General Description

The MAX2032 high-linearity passive upconverter or

downconverter mixer is designed to provide +33dBm

IIP3, 7dB NF, and 7dB conversion loss for a 650MHz to

1000MHz RF frequency range to support a multitude of

base-station applications. With a 650MHz to 1250MHz

LO frequency range, this particular mixer is ideal for

high-side LO injection architectures. For a pin-to-pin-

compatible mixer meant for low-side LO injection, refer

to the MAX2029.

In addition to offering excellent linearity and noise per-

formance, the MAX2032 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 MAX2032 requires a nomi-

nal LO drive of 0dBm, and supply current is guaranteed

to be below 100mA.

The MAX2032 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 PCB layout is

used for both frequency bands.

The MAX2032 is available in a compact 20-pin thin

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

Electrical performance is guaranteed over the extended

-40°C to +85°C temperature range.
