Digital Predistortion (DPD) IP Core
Overview
The next fifth-generation (5G) wireless networks promise connection speeds and data rates that are 100 times faster than current networks, as well as much enhanced signal and connection quality. As wireless communication systems evolve, the necessity for linearity in Power Amplifiers becomes more difficult. The use of Radio Frequency (RF) power amplifiers with wideband signals, such as WCDMA utilized in UMTS, results in the development of out-of-band emissions known as “Spectral regrowth.” This work employs the Digital Predistortion approach to increase PA efficiency and linearity.
Key Features
- Two transmitters consume less than 100 mW of power, which is one-tenth that of comparable FPGA-based systems
- Allows for the use of a high-efficiency power amplifier (PA) to minimize system power consumption
- Complete development toolbox for reducing time to market
- A collection of tried-and-true power amplifiers from well-known brands
- Detailed user instructions, a full application program interface (API), and control graphical user interfaces (GUIs)
Benefits
- Significantly improves transmitter power efficiency by enabling standards and regulatory compliance when using modern high-efficiency RF PA designs.
