WebIntroductionThis document provides guidelines for designing a power amplifier to achieve optimum performance with Maxim's radio frequency (RF) power amplifier (PA) linearizer (RFPAL) or other types of predistortion. Using RFPAL products (SC1894 and SC2200), an optimally-tuned PA can achieve up to 28dB of correction; thereby, allowing the amplifier
