Crest Factor Reduction (CFR) Technology, typified by Systems4Silicon's FlexCFR, is a highly adaptable solution geared towards minimizing the transmit signal envelope to boost RF power amplifier efficacy. This technology is particularly agnostic to communication standards and vendor independence, which empowers it to be integrated across any FPGA/SoC or ASIC platform effortlessly. FlexCFR is designed for dynamic reprogramming, accommodating any communication standard including multi-carrier signals.
One key advantage of FlexCFR lies in its ability to reduce amplifier costs by enabling the use of transistors with lower peak-power handling, thereby improving overall amplifier efficiency. The technology allows for dynamic configurations and operational flexibility, supporting single or multi-standard operations. Its operational capacity extends to adjusting the output signal Peak to Average Power Ratio (PAPR) to balance spectral emissions with in-channel performance.
Compatibility with other technologies like Digital PreDistortion (DPD) and envelope tracking marks FlexCFR as a versatile tool for enhancing power handling capabilities. It also features deterministic behavior which allows for reliable off-line system modeling for performance optimization. Accompanied by comprehensive documentation and expert support, FlexCFR ensures seamless integration and high-efficiency performance across various deployment scenarios.
