A Methodology for Analysis of mm-Wave Transmitter Linearization Trade-offs Under Spectrum Constraints
Conference contribution, 2018

This paper presents a simple method to estimate the efficiency and modulated RF performance for pre-distortion linearized PAs. The method is based on  AM/AM and AM/PM and DC power data obtained from single tone measurements or simulations. This method allows us to investigate the tradeoffs  between efficiency, output power, and predistortion complexity in PAs, under spectrum mask requirements. This is particularlyimportant for in mm-wave  applications. For demonstration, a 29 GHz GaAs PA has been modeled and used to study how biasing and pre-distortion complexity shape the output in  terms of power and efficiency.
