ABSTRACT:
The microwave radio frequency power divider/combiner comprises a signal input/output matching network coupled between a signal input/output and a central point of the power divider/combiner. M impedance transformer sections are connected in parallel to the central point and radiate outwardly therefrom with each of the M transformer sections having a first predetermined length, where M is integer greater than one. M pairs of impedance transformers sections are provided with each pair being coupled to an end of a different one of the M transformer sections remote from the central point with each of the transformer sections of the M pairs of transformers sections having the first predetermined length. N output/input ports are each coupled to an end of a different one of the transformer sections of the M pairs of transformer sections remote from the M transformer sections. Each of the N ports are matched to a given impedance and N is equal to 2M. 2N isolation networks include 2N termination impedances each having one terminal thereof connected to ground. The other terminal of each of a given N of the 2N termination impedances are coupled by a different one of first N impedance transformer sections to the N ports. The other terminal of each of the remaining N of the 2N termination impedances are connected by a different one of second N impedance transformer sections to the end of the N transformer sections remote from the central point with each of the first and second N transformer sections having the first predetermined length. N transmission line sections each having a second predetermined length different than the first predetermined length interconnect different adjacent ones of the 2N isolation networks in pairs.
