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.
