Introduction
Power amplifier (PA) linearization using digital pre-distortion (DPD) techniques
is critical for designers transitioning 3G systems to 3.9G and 4G. This application
note introduces the concept behind DPD, as well as how to use the Agilent
W1716 SystemVue DPD builder to do hardware verification. This software
module implements memory polynomial algorithms to correct wireless
components that have analog memory effects. Both simulation-based and test
equipment-based extraction and verification are possible. For the purposes of this
application note, SystemVue will be |
