3 dB 90 Degree Hybrid Couplers
A hybrid is a coupler that behaves as a power divider, providing an equal power split from input to output while creating a broadband 90° phase shift between the two outputs. RF ONE offer hybrid coupler in single, compact packages that provide low insertion loss, high directivity and tight coupling.
