固定衰減器放置在信號路徑中以減少功率傳輸,並設置為由遵循 T、L 或 Pi 配置的對稱電阻網絡固定衰減。它們的配置可以是波導、表面貼裝或同軸,並取決於在他們的應用中,他們可以是定向的或雙向的.
Fixed attenuators are placed in signal paths to reduce power transmission and are set at a fixed attenuation by a symmetrical resistive network that follows a T, L or Pi configuration. Their configuration can either be in waveguide, in surface mount or coaxial, and depending on their application, they can either be directional or bidirectional.
