Abstract

The invention provides a duplex amplifying module, a radio frequency front end module, a multi-mode radio frequency transceiver, a multi-mode terminal, and a method for sending signals of the multi-mode terminal. The power amplifying module includes a control module, and a low frequency amplifier and a high frequency amplifier which are connected with the control module, wherein the control module is used for sending a work mode indication signal to the low frequency amplifier or the high frequency amplifier according to a control signal from a baseband chip; the low frequency amplifier is used for receiving a low frequency transmission signal and the work mode indication signal sent by the control module, amplifying the low frequency transmission signal and then outputting in a work mode indicated by the work mode indication signal; and the high frequency amplifier is used for receiving a high frequency transmission signal and the work mode indication signal sent by the control module, amplifying the high frequency transmission signal and then outputting in a work mode indicated by the work mode indication signal. The multi-mode terminal comprises the power amplifying module, therefore, the area of a Printed Circuit Board (PCB) taken up by the multi-mode terminal is reduced effectively.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a power amplification module, a radio frequency front-end module, a multi-mode radio frequency transceiver, a multi-mode terminal and a method for sending signals by the multi-mode terminal. Background technique [0002] At present, in the architectural scheme of the Wideband Code Division Multiple Access (WCDMA) / Global System for Mobile Communication (GSM) dual-mode mobile phone, the general implementation method is as follows: figure 1 As shown, a baseband chip 100 , an antenna switch module 200 , a WCDMA / GSM dual-mode radio frequency transceiver 300 , a GSM power amplifier 410 , at least one WCDMA power amplifier 420 and a duplexer 430 are required. Since the International Telecommunication Union (ITU) has divided ten frequency bands (BANDs) in the WCDMA spectrum planning to meet the application requirements of WCDMA frequency bands in different countries and regions, if a WC...
