化合物半导体相比硅半导体具有高频率、大功率等优异性能,是未来5G通信不可替代的核心技术,将在5G通信中大量使用。性能优异的化合物半导体将在5G通信中大量使用5G智能手机将大量使用GaAs射频器件。GaAs射频功率放大器具有比Si器件更高的工作频率。随着移动通信频率不断提高,Si器件已不能满足性能要求,4G智能手机中的功率放大器已全部采用GaAs技术。未来5G通信将包括 Compared to silicon semiconductors, compound semiconductors have excellent performances such as high frequency and high power, and they are irreplaceable core technologies for future 5G communications, and will be used in large quantities in 5G communications. High-performance compound semiconductors will use a large number of 5G smart phones in 5G communications and will use GaAs radio frequency devices in large quantities. GaAs RF power amplifiers have higher operating frequencies than Si devices. With the increasing frequency of mobile communications, Si devices can no longer meet performance requirements, and power amplifiers in 4G smart phones have all adopted GaAs technology. Future 5G communications will include
