Abstract
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 leaka ge (ACP) characteristics. The power added efficiency (PAE) of the prop osed amplifier is 51% with an ACP of 45 dBc, which is the PDC standard (one of the Japanese mobile communication system's standards). This a mplifier can be applied to various systems merely by changing the ROM data.
