Claim 16:
17. A wireless device comprising:
a baseband processor configured to determine a control signal based at least in part on a communication from a base station; and
a transceiver including a power amplifier module and a multiplexer, the power amplifier module including a plurality of power amplifiers, and the multiplexer including a filter bank, a load circuit bank, a switch, and a bypass circuit, the filter bank including a set of filters, at least one filter of the set of filters configured to transmit a signal of a first frequency band and at least one other filter of the set of filters configured to transmit a signal of a second frequency band that differs from the first frequency band, the load circuit bank including a plurality of load circuits configured to reduce insertion loss in the multiplexer, the bypass circuit configured to connect an input port of the multiplexer to an output port of the multiplexer when the control signal determined by the baseband processor indicates the multiplexer is to operate in a non-carrier aggregation mode and an input signal is associated with the first frequency band, the switch configured to selectively connect a filter from the filter bank to a load circuit from a second load circuit bank, the bypass circuit further configured to connect the input port of the multiplexer to a load circuit of the plurality of load circuits when the control signal indicates the multiplexer is to operate in a carrier aggregation mode, and the multiplexer further including a second bypass circuit configured to connect the input port of the multiplexer to a second output port of the multiplexer when the control signal received from the baseband processor indicates the multiplexer is to operate in the non-carrier aggregation mode and the input signal is associated with the second frequency band, and the second bypass circuit configured to connect the input port of the multiplexer to a load circuit of a third plurality of load circuits of a third load circuit bank when the control signal indicates the multiplexer is to operate in the carrier aggregation mode.
