Abstract

A 0.degree. and 180.degree. hybrid power divider/combiner includes a first quadrature hybrid and two other quadrature hybrids arranged in tandem with one output port of the first hybrid connected to an input port of the tandem arrangement and the other output port thereof connected to a delay of electrical length equal to that of the tandem arrangement. When an input signal is applied to one input port of the first hybrid with the other port terminated, two signals of reduced amplitude which are either in phase or of opposed phase (dependent on which input port receives the input signal) are produced at the output of the tandem arrangement and delay.

Dependent claims

A power divider comprising in combination:

first, second and third quadrature hybrids, each having a pair of input ports and a pair of output ports, one of said output ports of said first hybrid being connected to one of said input ports of said second hybrid, said output ports of said second hybrid being directly connected to the input ports of said third hybrid for causing a signal passing through the combination of said second and third hybrids to exhibit a propagation delay L and a fixed relative to frequency 90.degree. phase shift;
and
a transmission line exhibiting a propagation delay L having no fixed relative to frequency phase shift coupled to the other output port of said first hybrid.
