Title: MOBILE TERMINAL FOR EXPANDING BANDWIDTH OF LTE B41 FREQUENCY BAND, AND METHOD THEREOF
Abstract:
A mobile terminal for expanding the bandwidth of an LTE B41 frequency band comprises a multi-mode multi-band power amplifier, a TXM module, a selection module, a first SAW wave filter, and a duplexer; when recognising that an inputted initial signal is a B41 signal, the multi-mode multi-band power amplifier determines the frequency band range of the B41 signal and selects a corresponding pin to output a B41 transmission signal, a B41 transmission signal of a first frequency band range outputted by the multi-mode multi-band power amplifier being outputted by means of the B7 signal duplexer to the TXM module for transmission, a B41 transmission signal of a second frequency band range outputted by the multi-mode multi-band power amplifier being outputted by means of the first SAW wave filter to the TXM module, and a B41 transmission signal of a third frequency band range outputted by the multi-mode multi-band power amplifier being outputted to the TXM module by means of the path of the selection module switching from the duplexer.
