Description

technical field [0001] The invention relates to the technical field of communications, in particular to a multi-carrier base station power amplification system. Background technique [0002] Wireless and mobile network operators face the ongoing challenge of building networks that efficiently manage high data traffic growth rates. The mobility and increased magnitude of multimedia content for end users requires end-to-end network adaptability that supports new services and the increased demand for broadband and flat-rate Internet access. In addition, network operators must consider the most cost-effective evolution of networks to 4G. Wireless and mobile technology standards are evolving towards higher frequency band requirements for increased peak rates and cell throughput. The latest standards supporting wireless and mobile technologies are HSPA+, WiMAX, TD-SCDMA and LTE. Contents of the invention [0003] In order to solve the above problems, the present invention dis...
