Abstract

본 발명은 모노리틱 쏘 듀플렉서(Monolithic SAW Duplexer)에 관한 것으로, 특히 고주파 신호를 송신하고 수신하는 장치에 포함되는 쏘 듀플렉서를 단일 공정에 의해 단일 칩으로 형성시키고, 송신 신호와 수신 신호, 즉 입/출력간의 신호 분리 특성을 개선하도록 하는 모노리틱 쏘 듀플렉서에 관한 것이다.
본 발명은 고주파 신호를 송신하고 수신하는 장치에 포함되는 쏘 듀플렉서를 단일 공정에 대해 단일 칩으로 형성시킴에 의해서, 제조 공정이 간단해지고, 원가가 절감될 뿐 아니라 이동 통신 등에 부합되는 소형화가 가능하며 신호 분리 특성이 개선으로 인하여 적용 제품의 기능을 향상시키는 등과 같은 효과가 있는 것이다.
