This filter is able to cover the frequency range from 3.42 to 3.76 GHz, which three Korean Mobile Communication companies; SKT, KT and LG are used for 5G.

SUNGSAN E&C has successfully developed the subminiature Band Reject Filter covering 3.5 GHz for 5G.

This filter is able to cover the frequency range from 3.42 to 3.76 GHz, which three Korean Mobile Communication companies; SKT, KT and LG are used for 5G.

Furthermore, compared to typically developed 5G band reject filter, the size is decreased 30% and the performance is advanced 30% through the cross arrangement technology of metal resonator.

It is an undeniable fact that developing Band Reject Filter is rather difficult.

Especially, metal resonator based products are heavily dependent on abroad.
As a result, SUNGSAN E&C believes that this band reject filter is expected to contribute a great deal to 5G industry.
