N-WAY DIVIDER/COMBINER, WITH N DIFFERENT FROM A POWER OF TWO, OBTAINED IN PLANAR, MONOLITHIC, AND SINGLE-FACE TECHNOLOGY FOR DISTRIBUTION NETWORKS FOR AVIONIC RADARS WITH ELECTRONIC BEAM-SCANNING ANTENNA

摘要

The present invention relates to a planar N-way powerdivider/combiner, wherein N is an integer different from apower of two, comprising a first port, which is to be coupledto a first transmission line having a first characteristicimpedance, N second ports, which are to be coupled each to acorresponding electrical load, and N division/combinationbranches, each coupled between the first port and acorresponding second port. All the electrical loads have oneand the same given load impedance. Furthermore, the planar N-way power divider/combiner is configured for dividing a firstelectrical signal present at input on the first port into Nsecond electrical signals, supplying at output each of the Nsecond electrical signals on a corresponding second port,combining N third electrical signals present each at input ona corresponding second port in a fourth electrical signal, andsupplying at output said fourth electrical signal at the firstport. The planar N-way power divider/combiner according to thepresent invention is characterized in that each of the Ndivision/combination branches comprises a corresponding firststage, a corresponding second stage, and a correspondingintermediate node between the corresponding first stage andthe corresponding second stage. The planar N-way powerdivider/combiner according to the present invention is furthercharacterized in that it also comprises, for each pair ofplanarly adjacent division/combination branches, acorresponding first uncoupling resistor, coupled between thecorresponding intermediate nodes and a corresponding seconduncoupling resistor, coupled between the corresponding secondports.
