General Description

The SC2200 belongs to the 4th-generation family of

RF PA linearizers (RFPAL) that provides increased

integration and functionality over the previous generations.

The device is a dual-path linearizer that is a fully-adaptive,

RFIN/RFOUT predistortion linearization solution

optimized for a wide range of amplifiers, power levels,

and communication protocols. It supports 2G to 4G

standards (FDD and TDD) from 698MHz to 2700MHz

as well as an expanded range of signal bandwidths from

60MHz down to 1.2MHz. The SC2200 accepts single-

ended RF signals to eliminate baluns and features a

mirrored pinout facilitating design of both paths. The

device uses the PA output and input signals to adaptively

generate an optimized correction function to minimize the

PA’s distortion. Using RF-domain analog signal processing

enables the SC2200 to operate over wide bandwidths

and with very low power consumption. The dual linearizer

is optimized for high-performance MIMO applications,

including small cells, active antenna, and distributed

antenna systems.
