3dB Hybrid Coupler 90°

90° Directional 3dB Hybrid Couplers

Narda-MITEQ manufactures a variety of 90 degree Directional 3dB Hybrid Couplers. Our 3dB 90 degree hybrid coupler is a specialized coupler that has two output ports that are 90 degrees out of phase with each other, splitting power equally between it's two output ports.

We offer both octave band and broadband coax directional hybrid couplers for your next RF project. Hybrid coupler models feature 30W to 50W RF power with 2kW to 3kW Peak.

For more information feel free to call us and discuss your needs for hybrid couplers with one of our design engineers.
