The Crest Factor Reduction (CFR) Technology developed by Systems4Silicon serves to enhance RF power amplifier efficiency by curbing the transmit signal envelope. This technology operates agnostically to communication standards, allowing it to be deployed across various systems with ease. FlexCFR is dynamically reprogrammable, making it highly adaptable to both single and multi-standard operations. By managing the Peak to Average Power Ratio (PAPR), it facilitates more efficient amplifier operation, thus reducing overall amplifier costs by enabling the use of more cost-effective power transistors.
FlexCFR's design ensures that it is vendor-independent, offering compatibility with any FPGA or ASIC platform, and includes flexible licensing terms to fit different business models. The technology minimizes its resource footprint, maintaining system efficiency without compromising performance. Its deterministic behavior allows for reliable off-line system modeling, which is advantageous for predicting and optimizing system performance.
This CFR solution is compatible with other technologies like digital predistortion (DPD) and envelope tracking, making it a comprehensive solution for power amplifier efficiency enhancement. Supported by advanced tools and knowledgeable radio systems engineers, it ensures smooth integration and robust operation in a wide range of deployment scenarios.
