Claims (3)
- RFID 태그로부터 RF 신호를 수신하는 1개 이상의 안테나;상기 안테나와 연결되고 상기 RF 신호를 증폭하는 1개 이상의 저잡음증폭부;상기 증폭된 RF 신호를 시간차를 두고 순차적으로 입력시키는 TDR(Time Defined Radio)부;상기 순차적으로 입력되는 RF 신호를 합산하는 RF합산부; 및상기 합산된 RF 신호를 변환시키는 컨버터를 포함하는 것을 특징으로 하는 TDR 구조의 RFID 트랜시버.
- 제 1항에 있어서, 상기 TDR부는스위칭 제어를 통하여 상기 증폭된 RF 신호의 주파수 대역을 시간축 상의 타임 슬롯들로 나누어 순차적으로 입력시키는 것을 특징으로 하는 TDR 구조의 RFID 트랜시버.
- 제 1항에 있어서, 상기 TDR부는입력 패쓰별로 다른 시간 단위를 할당하여 상기 증폭된 RF 신호들의 주파수 대역을 시간축 상에서 이동시키는 타임시프터(time shifter)로 구비되는 것을 특징으로 하는 TDR 구조의 RFID 트랜시버.
