Abstract
A distributed multiband coupling circuit including: a number n of first and of second terminals equal to the number of frequency bands; a third terminal and a fourth terminal; a number n of distributed couplers equal to the number of frequency bands, all couplers being identical and sized according to the highest frequency band, and each coupler including a first conductive line between first and second ports intended to convey a signal to be transmitted in the concerned frequency band, and a second conductive line coupled to the first one between third and fourth ports; a first set of resistive splitters in cascade between the third ports of the couplers, a terminal of the splitter associated with the first coupler being connected to the third terminal of the coupling circuit; and a second set of resistive splitters in cascade between the fourth ports of the couplers, a terminal of the splitter associated with the first coupler being connected to the fourth terminal of the coupling circuit.
