The Digital PreDistortion (DPD) Solution is a cutting-edge adaptive technology designed to enhance the power efficiency and performance of RF power amplifiers. This technology is scalable, offering optimization tailored to the specific bandwidth and performance needs of different platforms while supporting both FPGA and ASIC integrations. By allowing amplifiers to operate efficiently in their non-linear regions, the solution achieves more than 50% efficiency improvements, particularly when used with GaN devices in a Doherty configuration. With capabilities for multi-carrier and multi-standard transmissions, it is adaptable to various standards, including FDD, TDD, and 5G.
Crest Factor Reduction (CFR) Technology is an advanced solution aimed at limiting the transmit signal envelope to boost RF power amplifier efficiency. FlexCFR, as it is known, offers flexibility by being communications standard agnostic and vendor independent, thus it can be easily adapted for any FPGA/SoC or ASIC platform. This technology allows for single or multi-carrier operation and offers capabilities such as peak-to-average power ratio management that can be adjusted for different performance parameters like spectral emissions and in-channel transmissions. It provides a deterministic behavior that aids in system modeling and optimization, adapting dynamically to real-time requirements.
