RF High Stopband Rejection Small Size Telecom Band Reject Filters

1.Block signal transmission in a specific frequency range: the band-stop filter has no transfer function of zero, but has a transfer function minimum at the center cutoff frequency. Therefore, it can block the transmission of signals through its central frequency range.
2.Allow other frequency signals to pass: In addition to the center frequency range, the band-stop filter allows signals of all other frequencies to pass. This allows band-stop filters to be used to remove noise, interference and meet specific frequency response requirements.
3.Small wave distortion: compared with other types of filters, band-stop filters have smaller wave distortion. This means that it can better preserve the shape and amplitude of the signal passing through the filter.
4.Broadband signal processing: The band-stop filter can be used for the processing of broadband signals, because it can retain most of the frequency components and only block a specific frequency range.
5. Phase response: The phase response of a band-stop filter depends on its design and implementation, but is usually between a low-pass filter and a high-pass filter.
