Dual RF Power Amplifier Linearizer (RFPAL)

Fourth Generation Fully Adaptive RF PA Linearization Technology in a Single IC

Please check latest availability status for a specific part variant.


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.
