고주파 고압 표면실장형 감쇄기
●
특성
CQA545DD는 DC-6GHz, 전력 1W-5W, 고주파대역에서 사용가능한
마이크로스트립 회로용 감쇄기입니다.
표면을 SMA콘넥타, N콘넥터, PCB에 직접 솔더링해서 장착 할수 있게
설계되었습니다.
모든 부품이 주위 온도 변화(-55C에서 +155C)에 민감하게 반응하지
않는 ALN 세라믹 소자로 제조되어 오랜시간 동안 동작해도 안정적
입니다.
●
용도
이동통신기지국, 중계기, 고주파통신기기, 앰프, 단말기

Features and Applications
4GHz-1W surface mount small sized attenuators of 50 ohm
characteristic impedance.
CQA545DD 4GHz-1W power and high durability against
pulse / EMI accidents in small signal applications.
Face down configuration on strip line show better return loss
characteristics Long life and temperature stability of thin film
technology realize better performance at temperature range from
-55C to +155C. Applications include gain control circuit, isolation
circuit of power boost amplifiers at GHz, loss compensation of
transmission line of data communication systems, detecting
signal control of ATE-LSI test system-circuit board functional test
systems, industrial measurement electronics, medical scientific
electronics and miscellaneous communication systems.
