Embodiment Construction

[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0040] An embodiment of the present invention provides a duplex amplification module, which is applied to a transceiver channel of a multi-mode terminal. The duplex amplification module includes a power amplifier and a duplexer, wherein:

[0041] The power amplifier is used to amplify the signal of any one of the at least two frequency bands of the input signals of various modes before outputting to the duplexer;

[0042] The duplexer is used to output the amplified signal from the power amplifier; and / or to filter the signal of any one of the at least two frequency bands of ...

Abstract

The invention provides a duplex amplifying module, a multi-mode terminal, a radio frequency front end module, a multi-mode radio frequency receiving and sending chip, and a method for sending a signal of the multi-mode terminal. The duplex amplifying module includes a power amplifier and a duplexer, wherein the power amplifier is used for amplifying signals in any one of at least two frequency ranges of input various forms of signals and then outputting the amplified signals to the duplex; the duplex is used for outputting the signals amplified by the power amplifier, and/or for filtering signals in any one of at least two frequency ranges of received various forms of signals and then outputting the filtered signals. The duplex amplifying module and the multi-mode terminal comprising the same provided by the invention simplify radio frequency receiving and sending paths and greatly increase integration of the multi-mode terminal, therefore, the multi-mode terminal takes up a smaller area of a Printed Circuit Board (PCB).

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a duplex amplifying module, a multi-mode terminal, a radio frequency front-end module, a multi-mode radio frequency transceiver chip and a method for sending signals by the multi-mode terminal. Background technique [0002] In the current mobile phone communication system, the radio frequency front end of the mobile phone terminal is the key device for realizing signal transmission and reception. With the development of third-generation mobile communication technology (3G) and long-term evolution technology (LTE), telecom operators currently use multiple different standards, and the modes and frequency bands of each system are also different. The mainstream standards mainly include global mobile communications. System (Global System for Mobile Communication, GSM), Code Division Multiple Access system (Code Division Multiple Access, CDMA), Wideband Code Division Multiple Access s...
