The auctioning of the C-band for 5G use has raised concerns in North America that signals could interfere with aircraft altimeter operations. 5GTW asked a filter engineer and a test expert if there’s a problem and how to fix it.
Filters keep RF signals in line
In a video interview with 5G Technology World, Resonant’s Mike Eddy explains how RF filters keep wanted signals in an interference out. It’s all in the physics. As bandwidth gets crowded, governments auction more spectrum to accommodate our insatiable demand for data. While 3G used frequencies around 1 GHz, 4G expanded to around 2 GHz.…
5G RF filters need more innovation
RF filters have always been an important part of mobile devices, but in the 5G era, they are the key to unlocking the promised high bandwidth that will drive many 5G use cases.
5 things you need to know about 5G filters
by Robert Hammond, Resonant CTO, and Mike Eddy, Resonant VP Product Marketing & Business Development 5G networks operate in new and higher frequency bands, requiring new underlying technology and performance standards for RF filters. The industry must develop new resonating structures in order to filter at these high frequencies, and large bandwidths, with enough power…
