Cavity filters are electronic filters that are used in RF and microwave communication systems to selectively filter out unwanted frequencies from a signal. They are designed to provide a high level of selectivity and precision in filtering, making them ideal for use in applications where accurate frequency response is critical.
Cavity filters use a resonant cavity or a series of resonant cavities to selectively filter out specific frequencies from a signal. The cavity is typically made of a conductive material, such as aluminum or copper, and is designed to resonate at a specific frequency or range of frequencies.
Cavity filters can be designed as band-pass filters, which allow only a specific range of frequencies to pass through, or as band-stop filters, which block a specific range of frequencies. They can also be designed with multiple cavities, which can increase the level of selectivity and precision in filtering.
Cavity filters are commonly used in a variety of RF and microwave communication systems, including radios, satellite communication systems, and radar systems. They are also used in scientific research applications, such as particle accelerators and radio telescopes.
