1. An apparatus for wireless communication, comprising:
a processor circuit configured to generate, within a predefined frequency range, a first radio frequency (RF) signal based on received data for wireless RF transmission and having a first frequency subrange of the predefined frequency range and a second RF signal based on the received data, the second RF signal generated concurrently with the first RF signal and having a second frequency subrange of the predefined frequency range;
first and second transmit paths running through an amplifier via an input port of the amplifier and an output port of the amplifier and configured to generate and transmit, via a first antenna, a first transmit signal based on the first RF signal, and transmit, via a second antenna, a second transmit signal based on the second RF signal; and
a control circuit configured to:
adjust the first transmit path to a selected configuration state of a plurality of configuration states of the first transmit path, wherein each configuration state of the plurality of configuration states of the first transmit path corresponds to a different combination of frequency range and communication standard, and wherein the selected configuration state allows the first transmit signal to be transmitted within a selected frequency range using a selected communication standard.
