Under the state of the\nelliptical filter, the filter can get a smaller transition bandwidth and a\ntighter stop band fluctuation than Butterworth filters and Chebyshev filters.\nIn this regard, the elliptical filter is the best. This is a low-pass filter\nwith elliptical function of the 7th Order. The steepness of the filter is\nbetter than that of the filter. Features: 1. The low pass filter emits the\nsignal below the shut-off frequency, but the signal above the shut-off\nfrequency is weakened. 2. Harmonic suppression is often used in\nelectromagnetic signals or placed at the rear end of the mixer to filter out\nhigh-frequency noise and play a selective frequency. 3. The filter can greatly\nweaken the signal of 470 m and above, and the harmonic anti-interference\nability is approx. 50dbc Specification Parameters: 1. S11 \u0026lt;- 20 dB, standing\nwave ratio SWR \u0026lt;1.22; 2. S22 \u0026lt;- 20 dB, standing wave ratio SWR \u0026lt;1.22; 3. S21 \u0026gt;\n- 0.5 dB, insertion loss \u0026lt;0.5 dB; 4.
