433MHZ Low Pass Filter LPF Module

Description:
The low-pass filter allows signals below the cutoff frequency to pass, while signals above the cutoff frequency are attenuated. It is often used to suppress the high-order harmonics of electromagnetic signals, or to filter out high-frequency clutter at the back of the mixer to play the role of frequency selection. This filter can greatly attenuate signals above 470M, and the harmonic suppression capability is about 50dbc. Compared with several low-pass filters, under the same order conditions, the elliptic filter can obtain a narrower transition bandwidth and a smaller transition bandwidth than other types of filters such as Butterworth and Chebyshev filters. Stop band fluctuations, in this regard, the elliptic filter is optimal. This is a 7th-order elliptic function low-pass filter, and the filter steepness is better than other filters.
