C-Band Pass Filter play an important role in microwave circuits. Working attenuation is usually used to describe the amplitude characteristics of the filter, which is divided into: low-pass, high-pass, band-pass and band-reject filters. The amplitude-frequency characteristics of the four basic types of filters are shown below. APPLICATIONS Rejects terrestrial interference in C-Band (5G, Radar and
