The invention discloses a method for realizing frequency band match of a mobile terminal, the mobile terminal and a main board thereof. The mobile terminal comprises a radio-frequency transmitting module, a radio-frequency receiving module and a radio-frequency front end module which realize multi-band welding pad compatibility on a circuit board respectively; the mobile terminal also comprises a first connection and selection module and a second connection and selection module, wherein one end of the first connection and selection module is connected with a transmitting pin of one frequency band in a signal transceiving module, and the other end of the first connection and selection module is connected with the radio-frequency transmitting module; one end of the second connection and selection module is connected with a receiving pin of the frequency band in the signal transceiving module, and the other end of the second connection and selection module is connected with the radio-frequency receiving module; and the radio-frequency front end module is connected with the radio-frequency transmitting module and the radio-frequency receiving module. Through the method, the mobile terminal and the main board, the multi-band compatibility is realized by using a single-path radio-frequency transceiving circuit, the research and development cost can be lowered, and the research and development periods and people can be reduced.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing frequency band matching of a mobile terminal, a mobile terminal and a main board thereof. Background technique [0002] Modern communication technology develops very rapidly, not only there are many standards, such as GSM (Global system for Mobile Communication, Global System for Mobile Communications), CDMA (Code Division Multiple Access, Code Division Multiple Access) and WCDMA (Wideband Code division Multiple Access, broadband division Code multiplexing access), etc., and the same system needs to support a lot of frequency bands, such as CDMA needs to support 800M, 1.9G and 450M and so on. In order to support multiple frequency bands, a mobile terminal of a certain standard needs to add radio frequency transceiver circuits corresponding to each frequency band in the circuit design, but for a specific market and a specific operator, it often only us...
