Abstract:
A multiplexer device includes a single die, at least three acoustic filters and at least one antenna port arranged on the single die, and a shunt inductance connected between each of the at least one antenna port and ground. Each acoustic filter includes one of a transmit or receive filter corresponding to a predetermined radio frequency band. The at least one antenna port is connected to at least one antenna, respectively, where each of the at least one antenna port is further connected to at least one acoustic filter arranged on the single die, and is configured to pass RF signals corresponding to the predetermined RF band of the connected at least one acoustic filter. The shunt inductance provides impedance matching between each of the at least one antenna port and each of the at least one acoustic filter connect to the at least one antenna port.
