Problems solved by technology

The common practice of the existing RF power amplifier system is to use independent band switching; there is no communication interface function with high-speed data processing and no RF signal coupling port detection and control functions. This kind of power amplifier system has the following problems: using independent The band switching method, for products that need multi-band switching, its application is more complicated, and it is not conducive to the development of product miniaturization; without a communication interface for high-speed data processing, it cannot meet the various parameters of radio frequency signals For configuration and optimization, the flexibility is poor; without RF signal coupling port detection and control, it cannot meet the requirements of transplanting new technologies for RF power amplifiers
