5G NR is driving the trend of enhancing data rates and capacity through the use of spectrally efficient modulation waveforms and CA, resulting in high PAPR and wider bandwidths. To maintain higher efficiency, PA designers must adopt advanced linearization techniques that enable the amplifier active device to operate closer to saturation. Microwave Office circuit simulation software specializes in PA analysis and works directly with VSS system simulation software to quantify the linearity measurements such as CCDF, EVM, and ACPR that are essential in meeting these emerging technical challenges.
