Power Amplifier (PA) is the core device of RF front-end signal transmission, and its performance directly affects the communication quality and actual experience of the terminal equipment, which is in a relatively core position in the RF front-end chip.




CMOS PA is emerging as an alternative to GaAs PA in less demanding market segments







In recent years, under the trend of continuous miniaturization of terminal equipment design, the trend of modular RF front-end is becoming increasingly obvious. At the same time, with the continuous development of communication technology, the types of terminal equipment with wireless communication functions in wireless communication, radar, navigation, satellite communication, electronic countermeasures equipment and other systems are becoming more and more abundant, which has led to the rapid development of the RF PA market.

According to Yole, the market size of RF power amplifier modules was $5.376 billion in 2019, making it the largest segment of the RF front-end market. According to its forecast, the PA market will maintain a growth rate of 11% in the next six years, and the market size is expected to reach 8.931 billion US dollars by 2025.
