VIKING FLT-MFC-7893D-3740/4160 Terrestrial Interference C Band WiMAX/Radar Elimination Filter (3,740 - 4,160 GHz)

Summary

VIKING FLT-MFC-7893D-3740/4160 Terrestrial Interference C Band WiMAX / Radar Elimination Filter (3.740 - 4.160 GHz)

Historically, the solution for eliminating out-of-band interference (e.g. RADAR) has been to install a highly-selective bandpass filter. Specifically, a filter with a passband corresponding to that region's standard footprint (i.e. 3700-4200 MHz, 3400-4200 MHz, etc.)

However, not long ago, WiMAX began operating in the 3400-3800 MHz frequency band in many regions around the world. This common band operation causes in-band interference at C-Band receive sites that cannot be eliminated with "standard footprint" BPFs.

Example: WiMAX - operating at 3700 MHz - causes interference at C-Band receive site (where the footprint is 3700-4200 MHz). A standard footprint BPF will pass all frequencies from 3700 to 4200 MHz (i.e. - Including the WiMAX signal).

Solution: Install 7893D-3780/4200 bandpass filter that will provide 30db rejection at 3700 MHz and will pass all remaining C-band from (3780-4200) MHz.
