Abstract
An N-way RF power amplifier device includes a power divider, multiple first power amplifier circuits, multiple second power amplifier circuits, and a power combiner. The power divider divides an RF input signal into multiple differential signal pairs each including complementary first and second division signals. The first power amplifier circuits amplify the first division signals and the second power amplifier circuits amplify the second division signals in such a way that the amplified first division signals and the amplified second division signals have the same phase. The power combiner combines the amplified first and second division signals into an RF output signal.
