US 2018/0323754 A1 · POWER AMPLIFICATION DEVICE, TERMINAL HAVING THE SAME, AND BASE STATION HAVING THE SAME

Abstract

The method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for internet of things (IoT) are provided. The method includes intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The system includes a power amplification device capable of minimizing the effect of envelope impedance. The power amplification device may be incorporated in a terminal and a base station.
