IMPLEMENTING METHOD FOR MATCHING FREQUENCY BANDS OF MOBILE TERMINALS, MOBILE TERMINAL, AND MAINBOARD THEREOF

摘要

An implementing method for matching the frequency bands of the mobile terminals, a mobile terminal, and a mainboard thereof are disclosed. The mobile terminal involves a signal transmitting/receiving module with at least two frequency bands, a radio-frequency transmitting module, a radio-frequency receiving module and a radio-frequency front-end module. The mobile terminal also involves a first connection selection module and a second connection selection module. The implementing method for matching the frequency bands of the mobile terminals comprises the following steps. The multi frequency bands bonding pad compatibility is achieved respectively on the circuit board by the radio-frequency transmitting module, the radio-frequency receiving module and the radio-frequency front-end module One end of the first connection selection module is connected with the transmitting pin of the frequency band in the signal transmitting/receiving module when the mobile terminal has to work within a certain frequency band, and the other end is connected with the radio-frequency transmitting module One end of the second connection selection module is connected with the receiving pin of the frequency band in the signal transmitting/receiving module, and the other end is connected with the radio-frequency receiving module. The radio-frequency front-end module is connected with the radio-frequency transmitting module and the radio-frequency receiving module.
