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 method comprises the following steps: 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; when the mobile terminal has to work within a certain frequency band, one end of the first connection selection module is connected with the transmitting pin of the frequency band in the signal transmitting/receiving module, 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.
