Abstract
A power amplifier module includes a first phase shifter, a second phase shifter, and an electromagnetic shield. The first phase shifter includes a first transmission line assembly to shift a first amplified signal by a first phase angle. The second phase shifter includes a second transmission line assembly to shift a second amplified signal by a second phase angle. The electromagnetic shield is arranged to shield the first transmission line assembly from the second transmission line assembly. The power amplifier module may have, for example, Doherty amplifier configuration.
