Low Frequency Bandpass Filters Rf Cavity Filter Custom Band Pass Filter

The cavity filter is a microwave filter using a resonant cavity structure. A cavity can be equivalent to an inductor and a parallel capacitor to form a resonance stage to realize the microwave filtering function: Compared with other types of microwave filters, the cavity filter has a solid structure, stable and reliable performance, and a smaller size. , Q value is high, the high-end parasitic passband is far i. And its heat dissipation is good. Cavity filters include coaxial, comb, interdigitated, waveguide and other structural forms. It has a high Q value and is suitable for high-frequency filters. Production, generally covering the frequency of 0.1G ~ 42G, with stable structure, large power capacity, excellent performance and so on. Mainly used in wireless communication systems.
