Problems solved by technology

However, the internal matching of the radio frequency signal transmitting module 10 is completed by the power amplifier manufacturer, and it is inconvenient for the terminal manufacturers who directly use the radio frequency signal transmitting module 10 to carry out the internal matching and debugging of the low frequency band signal path or the high frequency band signal path. Matching debugging is performed on the main path (the branch connecting the output port O1 and the antenna load), since the main path is a common part of all frequency band signal paths, it will cause the performance of other frequency band signals except low frequency band signals and high frequency band signals. affected
