Band Stop Filter
The core feature of an RF band-stop filter is its ability to selectively and strongly attenuate signals within a specific frequency band while allowing passband signals outside that band to pass through smoothly. It is primarily used to suppress specific interference or spurious signals.
The core feature of an RF band-stop filter is its ability to selectively and strongly attenuate signals within a specific frequency band while allowing passband signals outside that band to pass through smoothly. It is primarily used to suppress specific interference or spurious signals.
Its core features include:
- Stopband Attenuation: Within the frequency band targeted for suppression (the stopband), it provides extremely high attenuation, effectively eliminating signals within that frequency range.
- Passband transmission: Within one or more passband frequency ranges outside the stopband, signals can pass through with extremely low insertion loss.
- Frequency response: Its characteristics are exactly opposite to those of a bandpass filter, which is why it’s also known as a “notch filter.”
- Core function: The primary role is to filter out or suppress specific interference signals present in the system (such as fixed radar interference and adjacent-channel interference) or unwanted spurious emissions.
- Key parameters include the stopband center frequency, stopband bandwidth, stopband attenuation depth, as well as the passband range and passband insertion loss.
