Abstract
The utility model provides a multiplexer module, and relates to the frequency selecting device of a direct amplification station for dual band mobile communication with a shared antenna. In the technical proposal, a first multiplexer corresponding with a low band and a sebond multiplexer corresponding with a high band are connected with an antenna through a low pass filter, a high pass filter or an aerial diplexing filter. Signals are divide$ into low band signals and high band signals by an antenna terminal after being transmitted into the low pass filter, the high pass filter or the aerial diplexing filter; the low band signals are di6ided into lOw band trAnsmitting signAls and low band receiving signals by the first multiplexer; and the high band signals are divided into high band transmitting signals and high band receiving signals by the second multiplexer. The utility model can be used as a 2G and 3G dual band frequency selecting module or as a GSM and DCS dual band frequency selecting module, and can be used for producing other dual band frequency selecting modules. Because the utility model only requires one multiplexer module for the dual band frequency selection, the cost of the frequency selecting device for the direct amplification station is reduced, and the volume of the direct amplification station is decreased.
