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.
