Cavity Filters

Cavity filters and passive electronic components selectively allow or block certain frequencies in a signal path. Their design includes resonant cavities tuned to specific frequencies by adjusting their physical dimensions. Engineers commonly use them in RF and microwave systems to eliminate unwanted frequencies and enhance the overall signal quality. These filters exploit the resonance properties of the cavities to achieve high levels of attenuation at specific frequencies while ensuring minimal loss for desired signals. Applications that require precise frequency control and high selectivity and isolation, such as wireless communication systems, radar systems, and satellite communications, rely heavily on cavity filters.
