Detailed Description
The MAX2009 adjustable predistorter can provide up to
12dB of ACPR improvement for high-power amplifiers by
introducing gain and phase expansion to compensate
for the PA
’
s gain and phase compression. The MAX2009
enables real-time software-controlled distortion correc-
tion, as well as set-and-forget tuning through the adjust-
ment of the expansion starting point (breakpoint) and the
rate of expansion (slope). The gain and phase break-
points can be set over a 20dB input power range. The
phase expansion slope is variable from 0.3
°
/dB to
2.0
°
/dB and can be adjusted for a maximum of 24
°
of
phase expansion. The gain expansion slope is variable
from 0.1dB/dB to 0.6dB/dB and can be adjusted for a
maximum of 7dB gain expansion.
The following sections describe the tuning methodology
best implemented with a class A amplifier. Other classes
of operation may require significantly different settings.
