FPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects
Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...

متن کاملAdaptive Predistorter Design for Nonlinear High Power Amplifiers
In this paper we present and compare several methods of compensating the nonlinearity of the RF front-end of a wireless system. The baseband compensation techniques have gained more attentions due to the simplicity of DSP implementation and also utilizing adaptive algorithms. Two baseband compensation techniques, namely predistortion and postdistortion (equalization) of the baseband signal are ...
متن کاملDigital predistortion of radio frequency power amplifiers using Kautz-Volterra model
Introduction: Power amplifiers (PAs) with high power efficiency are inherently nonlinear (NL). The requirements on linearity have increased since wideband signals with high peak-to-average ratios are used more in, e.g. mobile systems. Linearisation is, thus, necessary for high power efficiency of PAs. Digital predistortion (DPD) has attracted much interest since it is a cost-effective linearisa...
متن کاملDesign of class E power amplifiers by using scalable electro-thermal GaN HEMT model
In this paper, a scalable large signal GaN HEMT model including nonlinear thermal sub-circuit is described. Only two scalable parameters are needed in the Ids scalable model by introducing a simple correction factor. The established model can predict the I–V curves at different-in-size AlGaN/GaN HEMTs devices accurately. Small signal S-parameters and large signal load pull tests with on-wafer m...
