Abstract

Power  amplifier  (PA)  is  the  basic  block  of  an  RF communication  system.  PA  is  traditionally  a  nonlinear  device,  but any  increase  in  spectral  efficiency demands  the  use  of  a  linear  power  amplifier  in mobile  communications.  The  design  of  such  power amplifiers  with  a  constant  envelope  is  a  critical issue.  Linearization  techniques  help  in  improving the  performance  by  reducing  the  nonlinear  effects of  the  power  amplifier.  This  paper  explains complexity,  bandwidth  and  power  added  efficiency of  different  techniques  of  linearization,  which  can be  used  to  increase  the  PA  performance  by mitigating  the  non-linear  effects.   

Keyphrases: Bandwidth, complexity, efficiency, linearization techniques, power amplifier
