PROBLEM TO BE SOLVED: To downsize a multiplexer.SOLUTION: The multiplexer includes a first chip 12 in which a first filter 22 connected between a common terminal T0 and a first terminal T1 and a resonator 30 whose one end is connected to the common terminal without passing the first filter are formed and a second chip 14 in which a second filter 24 connected between the other end of the resonator and a second terminal and having a pass band lower than a pass band of the first filter, in which a resonance frequency of the resonator is higher than the pass band of the second filter. |
