Making 5G Phones easier to develop, geographically inclusive and more sustainable.
Increased data usage on smartphones is driving demand for more spectrum and more frequency bands. More bands mean more fixed frequency filters in mobile radio front ends. This is causing size, space and weight issues.
Fixed frequency filters are fundamental to the operation of all FDD wireless devices in use today. They ensure that their built-in transmitters and receivers can simultaneously send and receive signals whilst preventing self-interference from compromising their efficiency. As new frequency bands are introduced, the component count per device increases in line. This is untenable long-term.
