Abstract

The invention discloses a radio frequency power amplifier and a radio frequency power amplification system. The radio frequency power amplifier comprises a first amplifier, a first switch and a first capacitor; an input node of the first amplifier is configured to receive a radio frequency input signal, an output node of the first amplifier is configured to output a first radio frequency signal, a power supply node of the first amplifier is configured to be connected with a first end of the first switch, and a second end of the first switch is connected with a first power supply end; and the first end of the first capacitor is coupled to the first end of the first switch, and the second end of the first capacitor is connected with the grounding end. According to the radio frequency power amplifier and the radio frequency power amplification system, the loss of the whole radio frequency power amplification system can be reduced, so that the overall performance of the radio frequency power amplification system is improved.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to a radio frequency power amplifier and a radio frequency power amplification system. Background technique [0002] The radio frequency power amplification system is an important part of the radio frequency front end, and the electronic terminal can obtain higher radio frequency output power through the radio frequency power amplification system. [0003] At present, when the RF output power of the RF power amplifying system is high, the power supply voltage of the RF power amplifying system is generally adjusted in real time to adapt to the change of the RF output power of the RF power amplifying system to reduce the power consumption of the RF power amplifying system. Therefore, the working efficiency of the power supply supplying power to the radio frequency power amplification system is improved. The two most commonly used voltage management systems in the industry ar...
