Description
433MHZ LPF Low Pass Filter for RTL Based SDR Receiver A6X4The parameter index: 1. S11-20dB, SWR 1.22 in Bobbi; 2. S22-20dB, SWR 1.22 in Bobbi;
Compared several low-pass filter, in the condition of same order elliptic filter, filter compared to the Butterworth and Chebyshev filters 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 ellipse function low-pass filter, filter steepness of the other properties are the filter.
Low pass filter is made below the cutoff frequency signal through, but higher than the cutoff frequency of the signal is weakened. Harmonic suppression is commonly used in the electromagnetic signal, or put in a mixer rear end filter high frequency noise, frequency selective role . This filter can greatly weaken the signal of 470M or above, harmonic suppression capacity is about 50dbc.
