Abstract

The invention discloses a 5G power amplifier architecture for supporting non-independent networking. The amplifier comprises a first amplification group which is used for supporting a 5G frequency band and a 4G frequency band; a second amplification group used for supporting a 4G frequency band; and a third amplification group used for supporting a 4G frequency band. The frequency bands of the 4Gfrequency bands supported by the first amplification group, the second amplification group and the third amplification group are the same or different. According to the power amplifier, the amplification group supporting the 4G frequency band and the 5G frequency band is integrated. The simultaneous work of the 4G frequency band and the 5G frequency band of 5G non-independent networking is achieved, the area of a power amplifier chip and the area of a module are reduced, and integration is easy; the design complexity and cost of the radio frequency circuit are reduced; when the power amplifierprovided by the invention is used, a 5G N41 PA module does not need to be additionally arranged.

Description

technical field [0001] The invention belongs to the field of electronic components, and in particular relates to a 5G power amplifier architecture supporting non-independent networking. Background technique [0002] Radio Frequency Power Amplifiers (RF PAs) are an essential part of a wide variety of wireless transmitters. In the pre-stage circuit of the transmitter, the RF signal power generated by the modulating oscillator circuit is very small, and it needs to go through a series of amplification-buffer stage, intermediate amplification stage, and final power amplification stage to obtain sufficient RF power before feeding radiate to the antenna. The operating frequency of RF power amplifiers is very high, but the frequency band is relatively narrow. RF power amplifiers generally use frequency selection networks as load circuits. [0003] Two working modes are defined in the 5G standard: non-independent networking mode and independent networking mode. Among them, the no...
