dc.description.abstractW-CDMA 단말기에 적용 가능한 고효율 다중 모드 balanced 전력증폭기 구조를 제안하였다. 제안된 전력증폭기는 2단 증폭기로 구성되었고, 낮은 전력 영역 및 중간 전력 영역에서 효율을 증가시키기 위해 stage-bypass 기법과 부하 임피던스 스위칭 기법이 적용되었다. 이를 통해 4가지의 고효율 전력 모드를 구현하였으며, 제안된 구조를 실험적으로 검증하기 위해 GaAs HBT 전력증폭기를 설계 및 제작하였고, 측정하였다.;A highly efficient multi-mode balanced power amplifier(PA) structure is proposed for W-CDMA handset applications. The proposed PA has 2-stage amplifier configuration and the stage-bypass and load impedance switching techniques were applied to enhance power efficiency at medium power level as well as low output power level. Using the two techniques, four highly efficient power modes were realized. To demonstrate the usefulness of the proposed structure, a GaAs HBT balanced PA module was designed, fabricated, and measured.-
