3rd IMD - 3차 혼변조 특성 : 뛰어난 선형 성 보장

 

+5dBm 두개의 신호가 입력되더라도 -80dBc 이상으로 3차 혼변조(IMD3) 제거 성능 보장

 

강한 in band 간섭하에서 아주 작은 강도의 신호 녹화를 원신호 수준으로 수행할 수 있음

 

IMAGE REJECTION 특성: 여러 단계 의 믹서 를 거쳐 이미지 주파수 제거

 

일반적인 recorder는 tracking filter 또는 filter bank를 활용하여 single conversion 구조를 사용하므로 50dB 이하의

   

성능이 안 좋은 image rejection 성능을 보이나 MP7300은 multiple conversion 구조로 90dB 정도의 image rejection

   

성능을 보장
