Abstract : Three different designs of coaxial hybrid junctions having perf ormance analogous to a wave-guide magic-T are discussed. The experimental results with each type indicate that SWR's less than 2 looking into any arm are easily obtainable over a frequency band of about 10%. With carefully matched loads, decoupling greater than 70 db can be obtained. An application of the magic-T in phase measurement is described which is independent of the signal amplitude and is similar to the homodyne system of phase measurement.
