1. An apparatus for an antenna, comprising:
a first power amplifier and a second power amplifier; and
a common ground between the first power amplifier and the second power amplifier, wherein a Radio Frequency, RF, output of the first power amplifier is coupled to the common ground and an RF output of the second power amplifier is coupled to the common ground, wherein the RF output of the first power amplifier is shifted 180 degrees compared to the RF output of the second power amplifier, and the RF output of the first power amplifier and the RF output of the second power amplifier form a balanced feed for the antenna, and the RF outputs of the first and second power amplifiers are combined and arranged to be fed to the antenna.
