433MHz LPF Low Pass Filter with top notch Harmonic Suppression 50dbc or higher!
DESCRIPTION


Function:

Several low-pass filters are compared. Under the condition of the same order elliptic filter, the filter can obtain smaller transition bandwidth and narrower stopband fluctuation than Butterworth filter and Chebyshev filter. In this regard, the elliptic filter is the best. This is a low-pass filter with 7th order elliptic function. The steepness of the filter is better than that of the filter.


Features:

1. The low-pass filter passes the signal below the cut-off frequency, but the signal above the cut-off frequency is weakened.

2. Harmonic suppression is often used in electromagnetic signals or placed at the back end of the mixer to filter out high-frequency noise and play a frequency selective role.

3. The filter can greatly weaken the signal of 470m and above, and the harmonic suppression ability is about 50dbc.


Specification parameters:

1. S11 < - 20dB, standing wave ratio SWR < 1.22;

2. 2 < - 20dB, standing wave ratio SWR < 1.22;

3. 1 > - 0.5dB, insertion loss < 0.5dB;

4. Overall dimension of PCB (without SMA connector): 36mm × 16mm


Packing list:
