MARLBOROUGH, Mass., - APITech, a provider of RF and electromagnetic solutions for protection, power, and analog processing, have announced the release of a family of cavity filters for mitigation of 5G C-band interference in critical avionics systems.
Potential 5G interference with avionics sharing the same frequency band has impacted the rollout of 5G cellphone towers near airports.
APITech's Chief Technology Officer, Ian Dunn, recently spoke on this concern. "This is the first of many interference issues associated with higher frequency, broadband communications as wireless becomes the backbone of our ongoing digital transformation. APITech's core mission and targeted investments in RF protection address the broader issue of protecting critical electronics infrastructure from an increasingly dense, confused and overlapping electromagnetic spectrum".
As an example, APITech's BOM10648 cavity filter is designed to solve the emerging 5G C-band interference issue with radar altimeters and other critical avionics systems operating in the globally allocated 4.2-4.4 GHz aeronautical band. The passband of 4.2-4.4 GHz has less than 1 dB insertion loss and greater than 50 dB of signal rejection outside the aeronautical bandwidth with propagation delays of less than 2ns. This filter housing is 4 inches long and 1 inch square with connector and mounting options available to satisfy any installation requirement.
