PA in the wireless communication system
In wireless communication systems, PAs are located at the last stage of the transmission chain, to supply required RF power to antennas. The PA plays an important role, determining the quality of the communication service, in terms of signal quality and battery life.
The PA is the biggest contributor to the quality of the RF chain in communication systems. Linearity is extremely important in systems with high peak-to-average-power (PAPR) signals, as in modern wireless standards where OFDM is used for the digital modulation scheme, because the nonlinear response of the RF chain directly impacts error in the demodulation, resulting in poor bit-error-rate. Also, spectral regrowth created by nonlinearity can create interference in other bands. Thus, maintaining linearity of the RF chain is critical for the quality of wireless communication.
