초록
In this paper, we design hybrid limitter balanced(HLB) power amplifier with W-CDMA signal input. Balanced power amplifier is important component that decide efficiency in communication system. General balanced power amplifier has low efficiency and high distortion characteristics. Therefore, we embodied two path with limitter that amplitude path had high efficiency amplifier using limitter and phase path had high linear amplifier to improve such problem.
