Claim 3:
4. The RF module of claim 1, wherein:
the plurality of transmitters includes a first transmitter which comprises a first ET port and a first RF output;
the device further comprises an ET module (ETM) and a first power amplifier (PA) besides the RF module;
the ETM comprises an ET input and a first power output, and supplies power to the first power output according to signal obtained from the ET input, and the ET input is coupled to the ET output;
the first PA comprises a first RF input and a first power input respectively coupled to the first RF output and the first power output, and amplifies signal obtained from the first RF input by consuming power supplied from the first power input; and
during a first time interval, the first transmitter provides a first RF signal to the first RF output, and provides a first ET signal, which reflects an envelope of the first RF signal, to the first ET port; and the ET multiplexer relays the first ET port to the ET output.
