New generations wireless communication systems require linear efficient RF power amplifiers for higher data transmission rates. However, conventional RF power amplifiers are normally designed for peak efficiency under maximum output power condition. Consequently, when the power is backed-off from its maximum point, the amplifier efficiency drops...
