Abstract

The invention discloses a mobile phone transmitting system. The mobile phone transmitting system comprises a GaN radio-frequency power amplifier, a GaN smart boosting and modulating power supply module, a digital processing unit, a battery and an antenna, wherein the GaN radio-frequency power amplifier is used for performing power amplification on a received signal; the GaN smart boosting and modulating power supply module is used for raising a battery voltage to a working voltage, and performing high-voltage power supply and power supply modulation on the GaN radio-frequency power amplifier; and the digital processing unit is used for processing a communication signal, transmitting the communication signal to the GaN radio-frequency power amplifier through a transceiver, and controlling the GaN radio-frequency power amplifier and the GaN smart boosting and modulating power supply module in real time. According to the mobile phone transmitting system provided by the invention, the GaN radio-frequency power amplifier is taken as a power amplifier of a transmitting link. Compared with the prior art, the mobile phone transmitting system has the advantages of high efficiency, large broadband and small size.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a mobile phone transmitting system. Background technique [0002] With the advent of the era of big data, mobile phones, as transfer stations, carry the mission of information transmission. Mobile communication has entered the 4G era, and the annual shipment of 3G and 4G mobile phones has reached 300 million. 4G future terminal wireless technology has several characteristics: 1) high-order modulation, 2) broadband, 3) multi-carrier, 4) MIMO. While promoting information transmission, these characteristics also bring new problems to terminal equipment. [0003] According to the power consumption statistics of mobile phone communication links, 80% of the power consumption comes from the transmission link, and in the transmission link, the RF power amplifier accounts for 80% of the power consumption. At the same time, high-order modulation signals, such as HSPA+ and LTE, ar...
