The Digital PreDistortion (DPD) Solution by Systems4Silicon is crafted to elevate the power efficiency of RF amplifiers. This adaptive technology thrives on various platforms, being vendor-independent and offering scalability for FPGAs and ASICs. The solution can handle bandwidths over 1 GHz and supports a plethora of communication standards, including 5G, enabling operations with multi-carrier and multi-standard single-antenna transmissions. Operating efficiently across different transistor technologies, the DPD advances amplifier performance by compensating for memory effects and facilitating operation in non-linear regions, achieving efficiency improvements above 50% under certain configurations.
Systems4Silicon's Crest Factor Reduction (CFR) Technology is designed to optimize the power efficiency of RF amplifiers by controlling the transmit signal's envelope. This versatile solution is independent of the target device vendor and accommodates a variety of communication standards through dynamic re-programming. CFR technology proficiently reduces amplifier costs and enhances efficiency by increasing transmit power relative to bias power and is capable of adapting for single and multi-carrier operations. Furthermore, it exhibits 100% deterministic behavior, allowing for precise performance modeling and supports integration with Digital Predistortion and envelope tracking technologies.
