Summary: 
A power amplifier employing a novel linearizing technique is proposed and is applied to digital mobile communication systems. The amplifier offers both high efficiency and excellent adjacent-channel power leakage (ACP) characteristics. The power added efficiency (PAE) of the proposed amplifier is 51% with an ACP of 45 dBc, which is the PDC standard (one of the Japanese mobile communication systems standards). This amplifier can be applied to various systems merely by changing the ROM data.
