摘要： PROBLEM TO BE SOLVED: To decrease the bulk of a coupling structure and to improve reliability of measurements in a multiband coupling circuit.SOLUTION: A distributed multiband coupling circuit includes: 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. Each coupler includes 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. The coupling circuit further includes a first set of resistive splitters in cascade between the third ports of the couplers, wherein a terminal of the resistive splitter associated with the first coupler being connected to the third terminal.
