This paper focuses on the time domain envelope measurements based analysis of power amplifiers in order to improve both linearity and efficiency of microwave transmitters. First of all, a versatile time domain envelope test bench is presented. Then, two applications related to those RF PA measurements are reported. The first application concerns linearity characterization that can be specified in...
This paper presents a time domain envelope measurement system that enables the study and the optimization of high efficiency and linear power amplifiers by applying both envelope tracking and digital base band predistorsion techniques. A man focus of this paper is the description of the set up architecture along with its capability to achieve in depth investigations on the dynamic behavior of envelope...
