224–226 MHz Cavity Notch Filter | Band Reject Filter for VHF Communication
Description
Notch filter known also as a band stop filter or band stop filter, blocks and rejects frequencies that lie between its two cut-off frequency points passes all those frequencies either side of this range. It is another type of frequency selective circuit that functions in exactly the opposite way to the Band Pass Filter we looked at before. Band-stop filter can be represented as a combination of low-pass and high-pass filters if the bandwidth is wide enough that the two filters do not interact too much.
Applications
• Land Mobile Radio (LMR) systems
• Public safety communication networks (police, fire, emergency services)
• Military VHF communication systems
• Interference rejection in VHF repeaters
• RF testing and measurement setups
