Description
Claims (2)
- DCN용 안테나정합기(201A)와 PCS용 안테나정합기(201B)를 별도로 설치하고, 이들이 선택적으로 구동되어 DCN 모드의 신호 또는 PCS 모드의 신호를 정합하도록 하는 안테나정합부(201)와; 상기 안테나정합부(201)를 통해 수신되는 신호를 DCN용 듀플렉서(203A)와 PCS용 듀플렉서(203B)측으로 분리하여 출력하고, 이들을 통해 송출되는 신호를 상기 안테나정합기(201A),(201B)에 전달하기 위한 분리기(202)와; 엠에스엠(208)의 제어에 따라 상기 정합부(201)에 안테나정합기 선택신호를 출력하는 밴드선택부(213)를 포함하여 구성한 것을 특징으로 하는 이동통신 단말기의 안테나 매칭회로.
- 제1항에 있어서, 안테나정합부(201)는 DCN용 안테나정합기(201A)와 PCS용 안테나정합기(201B)가 각기 핀다이오드(PD1),(PD2)를 통해 안테나(ANT)에 접속되고, 이 핀다이오드(PD1),(PD2)가 상기 선택신호에 의해 제어되도록 구성된 것을 특징으로 하는 이동통신 단말기의 안테나 매칭회로.
