Cavity Filter Operating from 3700-4200MHz

A filter is a frequency-selective device that allows specific frequency components in a signal to pass while greatly attenuating other frequency components. Using this frequency selection effect of the filter, interference noise can be filtered out or spectrum analysis can be performed. A cavity filter is a microwave filter using a resonant cavity structure. A cavity can be equivalent to an inductor connected in parallel with a capacitor, thereby forming a resonant stage and realizing the microwave filtering function.

The cavity filter JX-CF1-3700M4200M-50S1 is specially designed according to the application, covering from 3700-4200MHz, with the feature of insertion loss less than 1.0dB, ripple less than 0.85dB, and Return loss more than 16dB.

As a cavity filter designer, Jingxin can support you to customize such kind of cavity filter which is characterized by high performance and high reliability. Do as promised, all the RF passive components from Jingxin have a 3-year guarantee.
