Claim 19:
20. The method of claim 19, wherein:
the device further comprises a power switch coupled between the ETM, the second power source and the second PA;
during the first time interval, the power switch relays the second power source to the second PA to supply the second PA;
during the second time interval, the power switch relays the ETM to the second PA to supply the second PA; and
the method further comprises:
during the second time interval, by the second transmitter, providing a second ET signal, which reflects an envelope of the second RF signal, to the second ET port; and, by the ET multiplexer, relaying the second ET port to the ET output to cause the ETM to supply the second PA according to the second ET signal.
