Abstract
Abstract A triple 3db, 90° coupler four-way power divider provides four balanced power outputs by combining therewith a fourth coupler, each of whose two inputs is connected to a different one of the two unbalanced outputs of the divider, with the two outputs of the fourth coupler and the two balanced outputs of the divider providing the four-way divided output power.
