The MAX2010 adjustable predistorter can provide up to
12dB of ACPR improvement for high-power amplifiers
by introducing gain and phase expansion to compen-
sate for the PA’s gain and phase compression. The
MAX2010 enables real-time software-controlled distor-
tion correction, as well as set-and-forget tuning through
the adjustment of the expansion starting point (break-
point) and the rate of expansion (slope). The gain and
500MHz to 1100MHz Adjustable

Detailed Description
Ground. Internally connected to the exposed paddle.
RF Gain Input. Connect ING to a coupling capacitor if it is not connected to OUTP. ING is
interchangeable with OUTG.
RF Phase Output. Connect OUTP to a coupling capacitor if it is not connected to INP. OUTP is
interchangeable with INP.
RF Phase Input. Connect INP to a coupling capacitor. This pin is interchangeable with OUTP.
Fine Phase-Slope Control Input 1. See the Typical Application Circuit.
Fine Phase-Slope Control Input 2. See the Typical Application Circuit.
Digital Coarse Phase-Slope Control Range Input 1. Set to logical zero for the steepest slope.
Digital Coarse Phase-Slope Control Range Input 2. Set to logical zero for the steepest slope.
Phase Breakpoint Control Input
Phase Expansion Output. Connect PBEXP to PBRAW to use PBIN as the breakpoint control voltage.
Uncompensated Phase Breakpoint Input
Gain-Control Supply Voltage. Bypass with a 0.01µF capacitor to ground as close to the device as
possible. Gain section can operate without V
Gain Breakpoint Control Input
Fine Gain-Slope Control Input
Coarse Gain-Slope Control Input
RF Gain Output. Connect OUTG to a coupling capacitor. OUTG is interchangeable with ING.
Exposed Ground Paddle. Solder EP to the ground plane.
Phase-Control Supply Voltage. Bypass with a 0.01µF capacitor to ground as close to the device as
possible. Phase section can operate without V
phase breakpoints 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 21° of phase expansion. The gain expansion slope is
variable from 0.1dB/dB to 0.53dB/dB and can be
adjusted for a maximum of 6dB 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.
