Abstract
A broadband 180.degree. 3 db hybrid coupler useful in mixing, combining and/or splitting circuits, the hybrid including slot line and microstrip hybrid components disposed on opposite planar surfaces of a dielectric substrate, one of the components having three ports and associated arms while the other component having a single port and arm, the hybrid providing signal coupling between the hybrid components except where the plane of symmetry of one of the hybrid components bisects the other hybrid component.
Claims3
slot line/microstrip hybrid, comprising:
- a dielectric substrate having two parallel planar surfaces;
- a relatively thin conductive coating disposed on one of said planar surfaces, a T-shaped three port slot line hybrid component being defined by a relatively narrow slot in said conductive coating;
- a split arm single port microstrip line hybrid component of conductive material disposed on the other of said planar surfaces, the longitudinal axes of the portions of the split arm hybrid component adjacent two coaxial arms of said T-shaped hybrid component being on opposite sides of and essentially parallel to the transverse arm of said T-shaped hybrid component.
