Abstract
A balun that includes a first conductor, a second conductor and a third conductor. The first conductor has a length of about one quarter wavelength of a selected center frequency. The first conductor also has a first end connected to a first balanced power amplifier output port. The second conductor has a length of about one quarter wavelength of the selected center frequency. The second conductor also includes a first end connected to a second balanced power amplifier output port and a second end connected a second end of the first conductor. The third conductor has a length of about one quarter wavelength of the selected center frequency. The third conductor has a first end connected to an antenna port and a second end connected to a ground potential.
