摘要： A duplexer includes a common terminal, receiving filters, a transmitting filter, and a hybrid having four terminals (terminals 1 to 4). A first terminal (terminal 1), which is one of the four terminals of the hybrid is connected to the common terminal, the receiving filters are connected to a second terminal and a third terminal to which a signal is transmitted if it is input from the first terminal, and a transmitting filter is connected to a fourth terminal (terminal 4) of the hybrid. Thus, it is possible to improve the isolation of the duplexer, while avoiding an increase in the number of parts as well as greater complexity.
