4.4 GHz to 4.8 GHz Nine-Section Bandpass Cavity Filter

Service Description

End Product

This high-performance bandpass filter is engineered with a nine-section architecture, specifically optimized for peer-to-peer (P2P) and public safety frequency management. Operating within a 400 MHz bandwidth (from 4.4 GHz to 4.8 GHz), the unit utilizes a combline design to deliver exceptional signal isolation, providing a minimum rejection of 55 dB at 5.0 GHz and 60 dB at 3.7 GHz. With a maximum insertion loss of only 1.25 dB, it ensures superior signal integrity for critical communication links.
