DIP SAW Filter

DIP SAW Filter是天線蓬勃發展時也跟著一併發展的產品。天線可以發射出1GHz以上的超高頻訊號,但由於高頻率的訊 號容易受到雜訊影響且除了中心頻外也會發射出其他的雜訊。所以透過表面聲波技術的濾波器可以有效的過濾掉不必要的頻率訊號。

Note:

ILmin is the minimum of the pass band attenuation. The center frequency

Fc is the mean value of the upper and lower frequencies at the 3dB filter attenuation level relative to the ILmin.
