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.
