Abstract

The invention discloses a radio frequency front-end module and a wireless communication device. The radio frequency front-end module comprises a substrate, a push-pull power amplifier chip and a power supply end, the push-pull power amplifier chip and the power supply end are arranged on the substrate, the push-pull power amplifier chip comprises a first differential amplification circuit, the first differential amplification circuit comprises a first differential transistor and a second differential transistor, the first differential transistor is configured to amplify a first radio frequency signal, and the second differential transistor is configured to amplify a second radio frequency signal; the output end of the first differential transistor is connected to the power supply end through a first metal wire arranged on the substrate, and the output end of the second differential transistor is connected to the power supply end through a second metal wire arranged on the substrate. The equivalent inductor formed by the first metal wire and the second metal wire is used for replacing the first inductor and the second inductor which are actually existing, impedance and insertion loss in the feeding process are reduced, the area of the radio frequency front-end module is reduced, and therefore the power conversion efficiency and the output power of the radio frequency front-end module are guaranteed.

Description

technical field [0001] The invention relates to the technical field of radio frequency communication, in particular to a radio frequency front-end module and a wireless communication device. Background technique [0002] The RF front-end is between the antenna and the RF transceiver, and is the core component of electronic terminal communication. The RF front-end includes filters, LNA (short for Low Noise Amplifier, low noise amplifier), PA (short for Power Amplifier, power amplifier), switches, and antenna tuning. The power amplifier is the core active device of the radio frequency front end, through which the electronic terminal can obtain higher radio frequency output power. The key performance goal of the fifth-generation mobile communication technology (5G) is to greatly increase the transmission rate compared with 4G. The 5G new technology needs to adopt a radio frequency front-end with higher frequency, larger bandwidth, and higher-order QAM modulation, so that it is...
