The Digital PreDistortion (DPD) Solution by Systems4Silicon is a cutting-edge technology developed to maximize the power efficiency of RF power amplifiers. Known as FlexDPD, this solution is vendor-independent, allowing it to be compiled across various FPGA or ASIC platforms. It's designed to be scalable, optimizing resources according to bandwidth, performance, and multiple antennae requirements. One of the key benefits of FlexDPD is its substantial efficiency improvements, reaching over 50% when used with modern GaN devices in Doherty configurations, surpassing distortion improvements of 45 dB.
FlexDPD is versatile, operating with communication standards including multi-carrier, multi-standard, and various generations from 2G to 5G. It supports both time division and frequency division duplexing, and can accommodate wide Tx bandwidths, limited only by equipment capabilities. The technology is also agnostic to amplifier topology and transistor technology, providing broad applicability across different setups, whether class A/B or Doherty, and different transistor types like LDMOS, GaAs, or GaN.
This technology integrates seamlessly with Crest Factor Reduction (CFR) and envelope tracking techniques, ensuring a low footprint on resources while maximizing efficiency. With complementary integration and performance analysis tools, Systems4Silicon provides comprehensive support and documentation, ensuring that clients can maximize the benefits of their DPD solution.
