New filter launched to Mitigate 5G interference in Avionics Systems
With concerns related to the recent launch of the faster high-band 5G cellphone service in the United States and its potential impact on aircraft safety, APITech™ (API Technologies Corp.), announced the release of a family of high-reliability cavity filters for mitigation of 5G C-band interference in critical avionics systems.
APITech is a provider of high-performance RF and electromagnetic solutions for protection, power, and analog processing. With over 70 years of heritage, APITech’s products are used by global defense, industrial, and commercial customers in the areas of commercial aerospace, wireless communications, medical, oil and gas, electronic warfare, radar, C4ISR, missile defense, harsh environments, and space.
“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”, commented APITech’s Chief Technology Officer, Ian Dunn.
APITech’s high-reliability BOM10648 cavity filter, for example 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.
APITech’s high-performance RF cavity filter solutions allow 5G C-band to take flight.
