Description
technical field [0001] The invention discloses an amplifier circuit with high power and low power consumption, and relates to the technical field of circuit design. Background technique [0002] RF systems in modern communication systems require low power consumption, high efficiency, and small size. In recent years, wireless communication has developed rapidly in the direction of large capacity, multi-level, multi-carrier, peak-to-average ratio, and broadband. Wideband digital transmission technology and modulation methods with high spectral efficiency are being used more and more widely. Performance puts forward more stringent requirements. As a key component of the radio frequency system, the power amplifier consumes a large proportion of the power in the whole radio frequency system. An inefficient power amplifier seriously affects the overall performance of the system. Therefore, designing high-efficiency RF power amplifiers is of great significance for reducing powe...
