Power Amplifier Nonlinearity at Ernestine Gibbs blog

Power Amplifier Nonlinearity. Typical power amplifiers nonlinearity results in spectral regrowth that spans over five times the bandwidth of the input signal. Predistortion techniques that are used to linearize such amplifiers will result in a similar (in terms of bandwidth) spectral regrowth. The conventional nonlinearity equalization (nle) method can effectively mitigate the nonlinear effects and provide superior ber performance. The central idea is to build a lookup table (lut) that directly captures the static compressive nonlinearity of the power amplifier (pa) and. In modern rf power amplifier applications, there are two conflicting design requirements: The need for linearity to preserve the fidelity of the signal and the demand for. In particular, we propose a statistical model that describes the nonlinear distortion as a function of the input signal’s. Nonlinearity is a major problem in high power amplifier (hp a), which results due to the limited physical structure of the hp a.
