The MAX2010 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 MAX2010
can provide up to 12dB of ACPR improvement for
power amplifiers operating in the 500MHz to 1100MHz
frequency band. Higher frequencies of operation can
be achieved with this IC’s counterpart, the MAX2009.
The MAX2010 is unique in that it provides up to 6dB of
gain expansion and 21° of phase expansion as the input
power is increased. The amount of expansion is config-
urable 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 software-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.
The MAX2010 comes in a 28-pin thin QFN exposed
pad (EP) package (5mm x 5mm) and is specified for
the extended (-40°C to +85°C) temperature range.
