Increasing demand is seen for the use of frequencies in the band 7 to 8 GHz throughout many industries. Satellites are progressing into a much higher portion of the available radio spectrum, while radar manufacturers are calling for a tighter filtering of their signals. Additionally, 5G and 6G research is looking at additional spectrum for use with new types of applications. The transmission of UAV data and the collection of data from IoT devices will be cleaner if the 7–8 GHz transmission is done without any contamination. Therefore, the choice of components becomes very much dependent on what the filter’s performances should be.

The engineers in these different industries expect their band pass filters to have low insertion loss, a consistent VSWR across the passband, and a sharp transition at the edges of the band. Keenlion’s new 7000-8000MHz band pass filter successfully meets all of these requirements: insertion loss ≤ 1.5dB, VSWR ≤ 2.0:1, and minimum rejection of at least 25dB at both 6GHz and 9GHz. The filter is constructed from oxygen-free copper to provide the best electrical conductivity over many years; also has SMA connectors with a 10W power rating allowing the filter to be used for both laboratory as well as field applications.
