Wireless 5G cellular communications networks are gobbling up bandwidth as people use more and more mobile data. Unfortunately, some of the frequency bands near 5G spectrum are already used at C-band by radar altimeters on commercial and military aircraft. Fortunately, Benchmark Lark has a solution that filters any 5G signals that might interfere with a radar altimeter—and a safe landing! With compact, surface-mountable filters such as the SD filters, potential radar altimeter interference can be removed without adding to the weight and size of the radar altimeters. Coaxial filters can even be added between coaxial cables and altimeters to make everything like new while meeting the strictest size, weight, and power (SWaP) requirements for military altimeters.
