Description:
A low-pass filter passes signals below the cutoff frequency, while signals above the cutoff frequency are attenuated. 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. This filter can greatly attenuate signals above 470M, and its harmonic suppression capability is about 50dbc.
Compared with several low-pass filters, the elliptic filter can obtain a narrower transition bandwidth and a sm
aller bandwidth than other types of filters such as Butterworth and Chebyshev filters under the same order. Stopband fluctuations, in this regard, elliptical filters are optimal. This is a 7th-order elliptic function low-pass filter. The filtering steepness is better than filters of other properties.
Parameter index:
1. S11 <-20dB, standing wave ratio SWR <1.22;
2. S22 <-20dB, SWR <1.22;
3. S21> -0.5dB, insertion loss <0.5dB;
4. PCB Dimensions (without sma connector): 36mm × 16mm
