Detailed Description

Introduction to Predistortion Using the

SC2200

Wideband signals in today’s telecommunications systems

have high peak-to-average ratios and stringent spectral

regrowth specifications. These specifications place high

linearity demands on power amplifiers. Linearity can be

achieved by backing off output power at the price of reduc-

ing efficiency. However, this increases the component and

operating costs of the power amplifier. Better linearity can

be achieved through the use of digital predistortion and

other linearization techniques, but many of these methods

are time consuming and costly to implement.

The SC2200 is a true RFIN and RFOUT solution where

the complex signal processing is done in the RF domain,

supporting modular power amplifier designs that are inde-

pendent of the baseband and transceiver subsystems.

This simple system-on-chip offers wide signal bandwidth,

broad frequency of operation, and very low power con-

sumption. It reduces development costs and speeds time

to market. Applicable across a broad range of signals—

including 2G, 3G, 4G wireless, and other modulation

types—the powerful analog signal processing engine is

capable of linearizing the most efficient power amplifier

topologies. The SC2200 delivers the required efficiency

and performance demanded by today’s wireless systems.

Wireless service providers are deploying networks with

wider coverage, greater subscriber density, and higher

data rates. These networks require more efficient power

amplifiers. Additionally, the emergence of MIMO, distrib-

uted architectures, and active antenna systems is driving

the increased need to support smaller, more-efficient

power amplifier implementations. Furthermore, a strong

push continues toward reducing the total capital and oper-

ating costs of base stations.
