1pcs433MHZ LPF low pass filter
Low pass filter is made below the cutoff frequency signal through, but higher than the cut-off frequency of the signal is weakened. Harmonic suppression is used in the electromagnetic signal, or put in a mixer rear end filter high frequency noise, play a selective role. This filter can greatly weaken the signal of 470M or above, harmonic suppression capacity of about 50dbc.
Compared with the low pass filter, in the condition of same order elliptic filter, filter compared to the Butterworth and Chebyshev filter and other categories, can obtain the transition bandwidth and smaller more narrow stopband fluctuations, in this regard, elliptic filter is optimal. This is a 7 order low-pass elliptic filter, filter steepness of the other properties are better than the filter.
