High-Linearity, 815MHz to 1000MHz Upconversion/

Downconversion Mixer with LO Buffer/Switch

General Description

Features

ꢀ 815MHz to 1000MHz RF Frequency Range

The MAX2031 high-linearity passive upconverter or

downconverter mixer is designed to provide +36dBm

IIP3, 7dB NF, and 7dB conversion loss for an 815MHz

to 1000MHz RF frequency range to support GSM/cellu-

lar base-station transmitter or receiver applications.

With a 960MHz to 1180MHz LO frequency range, this

particular mixer is ideal for high-side LO injection archi-

tectures. For a pin-to-pin-compatible mixer meant for

low-side LO injection, contact the factory.

ꢀ 7dB Noise Figure

In addition to offering excellent linearity and noise per-

formance, the MAX2031 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 MAX2031 requires a nomi-

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

to be below 100mA.

ꢀ Integrated RF and LO Baluns

ꢀ Low -3dBm to +3dBm LO Drive

ꢀ Built-In SPDT LO Switch with 49dB LO1 to LO2

Isolation and 50ns Switching Time

ꢀ Pin Compatible with the MAX2039/MAX2041

1700MHz to 2200MHz Mixers

ꢀ External Current-Setting Resistor Provides Option

for Operating Mixer in Reduced-Power/Reduced-

Performance Mode

The MAX2031 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 PC board layout

is used for both frequency bands.

ꢀ Lead-Free Package Available
