1. An apparatus comprising:

  • a first signal path for a first frequency band comprising a first power amplifier (PA) a first matching circuit and a first filtering circuit;

    a second signal path for a second frequency band, the second frequency band being different from the first frequency band; and

    a first switching circuit coupled to the second signal path to enable routing of a second signal from the second signal path to an antenna coupled to the apparatus such that at least a transmit switch of the first switching circuit is not subject to a transmit voltage swing.
