Coaxial, impedance-matched, four-port 180 DEG hybrid junctions for multioctave bandwidth operation include a gap in the outer shields of a port and a stub line at their interface for forming a uniform electric field within the gap. This gap and the interconnections between inner conductors and shields of certain ports and the stub, and the lengths of the port and stub lines are such that power input to a first port divides equally and in phase between two other ports with matched impedances and no power is at present at the fourth port. Similarly power fed into the fourth port divides equally, but 180 DEG out of phase, between the two other ports with matched impedances and no power is present at the first port.
