Zusammenfassung:This paper presents an adaptive wideband, digitally controlled RF envelope predistortion linearization system for high power amplifiers. The advantages of this predistortion architecture over conventional baseband digital approaches are that a 20/spl sim/33% wider correction bandwidth is achievable at the same clock speeds, and it can perform linearization without the need for a digital baseband input signal. Using 3-carrier CDMAOne and wideband multi-tone signals, the linearization performances for a 90W PEP LDMOS PA and a 680W PEP LDMOS PA were examined.
