NEW 433MHZ LPF low pass filter Harmonic suppression capability is about 50dbc

NEW 433MHZ LPF low pass filter Harmonic suppression capability is about 50dbc 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 for SMA connector): 36mm 16mm Packing list: Low pass filter module*1 NEW 433MHZ LPF low pass filter Harmonic suppression capability is about 50dbc 【 7th Order Elliptic Low Pass Filter】This low pass filter is designed with the 7th order elliptic function, providing superior steepness and performance compared to other filters like Butterworth and Chebyshev filters. 【Effective Signal Filtering】The low-pass filter effectively passes signals below the cut-off frequency while attenuating signals above the cut-off frequency. It is for ideal for reducing high-frequency noise and achieving frequency selectivity in electromagnetic signals or mixer applications. 【Harmonic Suppression Capability】With its harmonic suppression capability, this filter greatly weakens signals at 470m and above, delivering impressive harmonic suppression of about 50dbc. 【Precise Specifications】The filter meets strict parameters, high performance: S11 < -20dB, standing wave ratio SWR < 22; S21 < -20dB, standing wave ratio SWR < 1.22; S31 > -0.5dB, insertion loss < 0.5dB.
