Title:
MICROWAVE RADIO FREQUENCY POWER DEVIDER. COMBINER
Document Type and Number:
Japanese Patent JPS60208101
Kind Code:
A
Abstract:
@ The microwave radio frequency power divider/combiner comprises a signal input/output matching network coupled between a signal input/output (1) and a central point (X) of the power divider/combiner. M impedance transformer sections (C) are connected in parallel to the central point (X) and radiate outwardly therefrom with each of the M transformer sections having a first predetermined length, where M is interger greater than one. M pairs (D) 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 (1, ..., 16) 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 impe-dances 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 section 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.
