High-ratio, isolated microwave branch coupler with power divider, phase shifters, and quadrature hybrid

摘要

A microwave coupler which receives an input signal and converts it into two output signals is dislosed wherein the output signals exhibit the same phasing, the output signals are isolated, and a predetermined ratio exists between the power level of one output signal and the power level of the other output signal. An equal-split power divider transforms the input signal into intermediate signals which are then isolated and phase shifted. A quadrature hybrid combines the phase shifted signals and produces the output signals.
