중전력 고정 감쇠기

모듈이나 RF 시스템에서 출력 전력이 너무 높아 시스템이나 장비를 손상시킬 수 있는 경우, 감쇠기는 신호 파형이나 데이터를 교란하거나 변형시키지 않고 출력 전력을 낮출 수 있습니다. 감쇠기는 임피던스 정합을 개선하고 회로의 신뢰성을 확보할 뿐 아니라, 서로 다른 두 회로나 소자 간의 레벨을 조정하는 데에도 사용할 수 있습니다. Psatek는 1W에서 500W까지 동작하는 고정 감쇠기를 공급하며, 주파수 범위는 DC에서 67GHz까지이고 다양한 커넥터를 선택할 수 있습니다. 견적은 영업팀(sales@psatek.com)으로 문의해 주십시오.
