1200MHz to 2500MHz Adjustable

RF Predistorter

General Description

Features

The MAX2009 adjustable RF predistorter is designed to

improve power amplifier (PA) adjacent-channel power

rejection (ACPR) by introducing gain and phase expan-

sion in a PA chain to compensate for the PA’s gain and

phase compression. With its +23dBm maximum input

power level and wide adjustable range, the MAX2009

can provide up to 12dB of ACPR improvement for

power amplifiers operating in the 1200MHz to 2500MHz

frequency band. Lower frequencies of operation can be

achieved with this IC’s counterpart, the MAX2010.

♦ Up to 12dB ACPR Improvement*

♦ Independent Gain and Phase Expansion Controls

♦ Gain Expansion Up to 7dB

♦ Phase Expansion Up to 24°

♦ 1200MHz to 2500MHz Frequency Range

♦ Exceptional Gain and Phase Flatness

♦ Group Delay <1.3ns (Gain and Phase Sections

Combined)

♦

0.04ns Group Delay Ripple Over a 100MHz Band

The MAX2009 is unique in that it provides up to 7dB of

gain expansion and 24° of phase expansion as the

input power is increased. The amount of expansion is

configurable through two independent sets of control:

one set adjusts the gain expansion breakpoint

and slope, while the second set controls the same

parameters for phase. With these settings in place, the

linearization circuit can be run in either a static set-and-

forget mode, or a more sophisticated closed-loop

implementation can be employed with real-time soft-

ware-controlled distortion correction. Hybrid correction

modes are also possible using simple lookup tables to

compensate for factors such as PA temperature drift

or PA loading.

♦ Capable of Handling Input Drives Up to +23dBm

♦ On-Chip Temperature Variation Compensation

♦ Single +5V Supply

♦ Low Power Consumption: 75mW (typ)

♦ Fully Integrated into Small 28-Pin Thin QFN

Package

*Performance dependent on amplifier, bias, and modulation.
