A novel analog predistortion linearization technique for RF-in RF-out power amplifier
Predistortion is a popular technique for the linearization of high power amplifiers. Among predistortion techniques, while digital predistortion (DPD) enjoys advantages of configurability and improved performance, analog predistortion (APD) has advantages such as lower footprint and high bandwidth operation. As baseband information is not required for APD, it finds its application in repeater systems, where incoming RF signal needs to be re-transmitted using high power amplifier. This paper presents a modified analog predistorter solution for high power amplifier, which provides better solution at lesser power back-off leading to optimum utilization of high power amplification unit.
