Some New Changes 5G Brings To PA

Click: 14Date: 2019-09-11Come from: Aimer Liu

  

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

     The PA 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 power amplifiers in the PA module. Therefore, with the development of 5G networks, the complexity of the PA module will continue to increase.
