AMD provides a market leading DPD solution that reduces CapEx and OpEx
Digital Pre-Distortion (DPD) is one of the most fundamental building blocks in wireless communication systems today. It is used to increase the efficiency of Power Amplifiers. By reducing the distortion created by running Power Amplifiers in their non-linear regions, Power Amplifiers can be made to be far more efficient. Wireless base stations not employing CFR or DPD algorithms typically exhibit low efficiency, and therefore high operational and capital equipment costs. A typical Class AB LDMOS Power Amplifier with WCDMA waveforms may have approximately 15-20% efficiency. With CFR and DPD turned on, this efficiency can grow to as much as 40%, resulting in tremendous savings in CapEx and OpEx for network operators. With later generations of Power Amplifier design leveraging Doherty architectures, efficiencies in the 50%+ range with AMD DPD are possible.
The DPD core reduces implementation time by providing a high performance DPD solution to customers as a parameterizable core rather than one that needs to be customized by hand. Furthermore, AMD DPD is tuned for implementation in AMD FPGAs, resulting in a very small FPGA footprint and the lowest cost FPGA solution available today. DPD IP now predistorts and handle long term memory effects seen with Gallium Nitride (GaN) amplifiers, enabling customers to excellent efficiency while meeting stringent spectral emission mask (SEM) requirements as well as Error Vector Magnitude (EVM) at all power levels.
