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.
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
