DIP SAW Filter

DIP SAW Filter is a product that develops along with the boom of antennas. Antennas can emit ultra-high frequency signals above 1GHz, but because high-frequency signals are easily affected by noise and also, the antennas will emit noise with center frequency. So through the filter using surface acoustic wave technology can effectively filter out unnecessary frequency signals.

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.
