Abstract
Methods and apparatus for implementing a power amplifier circuit assembly an uneven power splitter which feeds two power amplifiers of different amplifier classes are described. By supplying different amounts of power to different amplifier circuits having different performance curves, an overall combined amplifier performance having a relatively uniform, e.g., flat, performance curve over a wide range of frequencies is achieved. In at least some embodiments one of the amplifiers is a class B power amplifier and the other amplifier is a class C power amplifier. In some but not necessarily all embodiments a phase shift is introduced on a signal path to one of the power amplifiers to compensate for a difference in phase shifts introduced by the power amplifiers which are used in parallel.
