    摘要： A duplexer includes: a transmission filter and a reception filter that have different band center frequencies from each other; a phase matching circuit that performs phase matching on the transmission filter and the reception filter; and a laminated package that includes a first layer on which the transmission filter, the reception filter, and the phase matching circuit are mounted. In this duplexer, the first layer includes a first ground line pattern that is connected to a ground of the transmission filter, a second ground line pattern that is connected to a ground of the reception filter, a third ground line pattern that is connected to a ground of the phase matching circuit, and signal line patterns. The laminated package also includes a second layer that is located below the first layer. The second layer includes a partition ground line pattern that is located between the signal line patterns, a signal foot pad for external connection, and a ground foot pad. The first ground line pattern and the second ground line pattern are connected to the partition ground line pattern via the ground foot pad.

    摘要： A duplexer includes an unbalanced transmitting filter; a balanced receiving filter; a transmitting port connected to the transmitting filter; and a first receiving port and a second receiving port connected to the receiving filter. The duplexer also includes an electromagnetic coupling portion connected between the transmitting port and the first receiving port and between the transmitting port and the second receiving port. The electromagnetic coupling portion adjusts the phase between electric power that flows from the transmitting port to the first receiving port and electric power that flows from the transmitting port to the second receiving port.
