Abstract

A multiplexer includes first and second nodes, an inductor, a first transmit/receive filter, and second and third transmit filters. The inductor is connected at one end to the first node and at the other end to the second node. The first transmit/receive filter is connected to the first node without the inductor interposed therebetween and uses the transmit and receive bands of band A as a pass band. The second transmit filter is connected to the second node and uses the transmit band of band B as a pass band. The third transmit filter is connected to the second node and uses the transmit band of band C as a pass band.
