A power amplifier (PA) line-up (210) and a method (500) for more efficiently utilizing battery power are disclosed. PA line-up (210) includes a driver (220), a matching circuit (214), and a PA (230) coupled to a matching circuit (216), wherein matching circuit (216) is configured to be coupled to a filter (260). PA line-up (210) includes a transmission line (260) coupled to matching circuit (216) and a switch (262) configured to selectively couple driver (220) to either matching circuit (214) or matching circuit (216) such that signal (205) is capable of by-passing PA (230) when signal (205) does not need to be amplified by PA (230). Furthermore, PA line-up (210) may include a second transmission line (250) so that signal (205) is capable of by-passing a driver (220) and a PA (230) when signal (205) does not need to be amplified by driver (220) and PA (230).
