1. A method for multiplexing, the method comprising:
providing a multiplexer to support carrier aggregation with a common antenna, the multiplexer including a low-band filter, a mid-band filter, a first high-band filter, and a second high-band filter, each filter having a respective input node, the multiplexer further including a common output node associated with the common antenna; and
performing one or more transmit operations including a low-band transmit operation with a low-band power amplifier with a switchably selected one of a plurality of low-band frequency bands such that an output of the low-band power amplifier is provided to the input node of the low-band filter without a switch, a mid-band transmit operation with a mid-band power amplifier with a switchably selected one of a plurality of mid-band frequency bands such that an output of the mid-band power amplifier is provided to the input node of the mid-band filter without a switch, a first high-band transmit operation with a high-band power amplifier with a switchably selected one of a plurality of high-band frequency bands such that a first output of the high-band power amplifier is provided to the input node of the first high-band filter without a switch, and a second high-band transmit operation with the high-band power amplifier with another switchably selected one of the plurality of high-band frequency bands such that a second output of the high-band power amplifier is provided to the input node of the second high-band filter without a switch.
