Abstract

A multiplexer includes a common port, multiple filter branches and at least one switch included in a switched filter branch of the multiple filter branches. The filter branches are connected to the common port, and each filter branch corresponds to at least one predetermined frequency band and filters a radio frequency (RF) signal according to the corresponding at least one predetermined frequency band. In a first switch state of the at least one switch, the switched filter branch includes a high-Q filter having multiple high-Q components for improving roll-off of the filtered RF signal, and in a second switch state of the at least one switch, the switched filter branch includes a low-Q filter having multiple low-Q components that support a very high bandwidth for filtering the RF signal.
