Quadrature hybrid coupler design

( New for March 2020) Hybrid couplers are the special case of a four-port directional coupler that is designed for a 3-dB (equal) power split. Hybrids come in two types, 90 degree or quadrature hybrids, and 180 degree hybrids. Why isn't there a "45 degree hybrid" you ask?.

• Octave and multi-octave designs • Low insertion loss and VSWR • High isolation • Drop-in and coaxial models • Rugged packaging • Couplers comply with MIL-P-23971.
