1.A low-pass filter passes signals below the cutoff frequency, while signals above the cutoff frequency are attenuated.

2.Commonly used for the suppression of high-order harmonics of electromagnetic signals, or placed at the back of the mixer to filter out high-frequency clutter, which plays the role of frequency selection.

3.This filter can greatly attenuate signals above 470M, and its harmonic suppression capability is about 50dbc.

4.The filtering steepness is better than filters of other properties.
