Abstract

The invention relates to a radio frequency amplifier module and an amplification method thereof. The radio frequency amplifier module comprises a downlink amplifier unit, an uplink amplifier unit and a radio frequency switch connected between the downlink amplifier unit and the uplink amplifier unit. The downlink amplifier unit comprises a radio frequency amplifier circuit which is used for carrying out power amplification processing on a radio frequency signal input by a downlink and outputting the processed signal, and an auxiliary circuit which is used for detecting input power, positive output power and negative output power of the radio frequency amplifier circuit. The uplink amplifier unit comprises a low-noise amplifier circuit which is used for carrying out low-noise amplification processing on the radio frequency signal input by an uplink and outputting the processed signal. According to the module and the method, the amplification efficiency is high, the good linearity is achieved, a performance index demand of a TD-LTE (Time Division Long Term Evolution) base station system can be satisfied, and the module and the method have relatively good application prospect.

Description

[0001] 【Technical field】 [0002] The invention relates to power amplification technology, in particular to a radio frequency amplification module in a TD-LTE system and an amplification method thereof. [0003] 【Background technique】 [0004] With the rapid development of mobile communications, the requirements for network construction are getting higher and higher. In order to better meet the needs of users for high-speed services, network operators such as China Mobile and industry departments continue to increase the construction of TD-LTE (Time Division Long Term Evolution, Time Division Long Term Evolution) networks. Among them, TD-LTE base station technology plays an important role in network construction. The base station, that is, the public mobile communication base station, is a form of radio station, which refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication switching center in a certain radi...
