This cavity filter has a operating frequency range of 16 GHz to 30 GHz, with very low insertion loss and VSWR to help ensure clean signal transmissions. It has a >15 dB rejection from 0 to 15.5 GHz, as well as from 30.5 GHz to 38 GHz, and therefore effectively stops or attenuates signals that are outside of the operating band. It is silver surface treated due to being made of aluminum. It uses a 2.92 mm female connector, has a 50 ohm impedance. This Cavity Filter is designed for proper performance in the high frequency testing and communications systems. Since we manufacture own production line, we offer customized performance, dimensions, and interfaces to suit your project needs.
