HK-VSOF01 VHF Single Band-pass Filter can improve the selectivity of receivers. When multiple transmitters share one antenna, it can help improve the isolation degree between transmitters, suppress out-of-band noise and avoid intermodulation interference

HK-VCSF01 Square-cavity Band-pass Filter applies to building civil aviation communication system. It can improve the selectivity of transceivers.

HK-VCDF01 VHF Dual-cavity band-pass filter can increase the radio spectrum utilization rate, and improve useful signals’ purity of radio spectrum as well as suppress out-of-band noise and avoid intermodulation interference effectively.
