Broad-Band Hybrid Junctions (Correspondence)

A coaxial version of the wide-band stripIine magic T described by E. M. T. Jones in the March, 1960 issue of these Transactions was developed jointly at the Mullard Research Laboratories and the Laboratories of the General Electric Company, England, some years ago. It has proved a powerful component in the design of broad-band receiver circuits and has the advantage of small size and geometrical symmetry in addition to wide frequency coverage.
