KYOCERA AVX’s has expanded its 3dB 90° hybrid couplers – the DB0402 adds a miniature 0402 size package to the family which already includes the DB0603, and DB0805 series – engineered to meet the growing demands of high-frequency wireless systems across industrial, automotive, telecommunications, and telemetry sectors. As wireless technologies continue to advance at pace, the need for components that can deliver consistent, high-frequency performance in ever-smaller footprints has never been greater. The DB series from KYOCERA AVX answers this call with a robust, space-saving solution that doesn’t compromise on power or precision.

These hybrid couplers are special four-port directional couplers designed to split input signals into two equal-amplitude outputs with a 90° phase shift, enabling precise signal control and monitoring in compact RF systems. With their miniature footprints, robust construction, and excellent electrical performance, the DB series couplers are ideal for next-generation wireless infrastructure and compact embedded designs.
