Predistortion- and development-platform for multi-input RF power amplifiers

Singerl, Peter; Magesacher, Thomas LU and Mataln, Martin (2016) 11th European Microwave Integrated Circuits Conference, EuMIC 2016 In EuMIC 2016 - 11th European Microwave Integrated Circuits Conference p.29-32
Abstract

We present a real-time digital predistortion (DPD) and RF power amplifier (PA) development platform with separate synchronous and coherent RF channels to evaluate multi-input RF PAs with realistic modulated test signals. The platform is based on a Xilinx FPGA and wideband analog frontends to support signal bandwidths up to 312.5 MHz. We describe both the implemented hardware as e.g. DPD core and digital splitter and the algorithms used to estimate the required DPD parameters. Furthermore we demonstrate the wideband linearization and efficiency optimization capabilities on two different 2 GHz Doherty PAs.
