Abstract
A first transmit path, a second transmit path, and a third transmit path are disclosed. The first transmit path includes a first radio frequency (RF) power amplifier (PA) and alpha switching circuitry, which is coupled to an output from the first RF PA. The second transmit path includes a second RF PA and beta switching circuitry, which is coupled to an output from the second RF PA. The third transmit path includes a third RF PA.
