Some New Changes 5G Brings to power amplifier

The 5G wireless revolution is bringing tremendous changes to the RF design, and rf power amplifier for cell phones and radio base stations are no exception. First, the rf amplifier chip in a 5G wireless application is quite different from the microwave amplifier chipused in a 4G network.

The PA power amplifier module has become the cornerstone of integration because its presence further reduces the number of components in the 5G RF front end. The 5G network has more frequency bands and requires more RF switches, filters and rf amplifiers in the PA power amplifier module. Therefore, with the development of 5G networks, the complexity of the PA module will continue to increase.
