Latest Patents
Marwen holds a patent for a "Multi-rate multistage digital compensator for nonlinear systems." This adaptable, multistage, multi-rate digital predistortion system increases the accuracy of the distortion applied to a power amplifier input signal. The system is designed to be implemented using a reduced circuit area by minimizing the number of coefficients used in the models that generate the distortion compensation signal. Additionally, it features an improved digital predistortion adaptation engine that enhances the adjacent channel leakage ratio of the system. The technology compensates for nonlinear impairments in analog and RF circuits, improving metrics such as Error Vector Magnitude (EVM), Adjacent Channel Leakage Ratio (ACLR), Spectrum Emission Mask (SEM), and power consumption. An example of the application of this technology is in radio frequency power amplifiers (RF PA).
