Digital Pre-Distortion (DPD) is a crucial technology utilized in modern wireless communications to improve the linearity of RF power amplifiers. Faststream Technologies has developed advanced DPD solutions optimized for use with Gallium Nitride (GaN) amplifiers, which are renowned for their efficiency yet challenging linearity characteristics. DPD effectively counters the memory effects inherent in these amplifiers, ensuring signal integrity and compliance with spectrum emission mask (SEM) and error vector magnitude (EVM) standards.
Incorporating DPD allows for significant improvements in power efficiency by enabling amplifiers to operate close to saturation without the typical nonlinear distortion. This translates to lower operational costs and enhanced performance in high-speed wireless networks such as 5G, where bandwidth demands are extraordinarily high.
Faststream's DPD solutions are tailored for seamless integration with FPGA systems, particularly Xilinx devices, providing a compact, cost-effective implementation option. This integration facilitates rapid prototyping and commercialization, supporting a faster time-to-market for telecom equipment manufacturers.
