The coupler comprises resistors which are adapted to sum and/or divide the incoming and/or outgoing signal. The resistors are arranged at or in the connector. A sum port and/or at least two dividing ports are arranged on a substrate. ## Claims ### Claim 1 A coupler, in particular a resistive coupler, wherein a sum port and/or at least two dividing ports are arranged on a substrate, wherein all ports are at least partially arranged at or in a connector, wherein resistors, which are adapted to sum and/or divide an incoming and/or outgoing signal, are arranged at or in the connector, wherein the connector comprises a central conductor, wherein the central conductor is connected to the at least one dividing port in a flat manner, wherein the connector is a coaxial connector comprising a shell and a dielectric material configured to separate the shell from the central conductor, wherein the shell of the connector is fixed to a reference-signal plane of the substrate, and/or wherein a body of the connector and the shell connected to the body of the connector are fixed to a reference-signal plane of the substrate. ### Claim 2 (depends on 1) The coupler according to claim 1, wherein the resistors are ceramic resistors and/or wherein at least two resistors comprise a common ceramic substrate. ### Claim 3 (depends on 2) The coupler according to claim 2, wherein the common ceramic substrate is arranged within a divided section of the shell. ### Claim 4 (depends on 2) The coupler according to claim 2, wherein the common ceramic substrate is penetrated by the central conductor of the connector. ### Claim 5 (depends on 1) The coupler according to claim 1, wherein at least one of the resistors comprises a thin-film resistive element. ### Claim 6 (depends on 1) The coupler according to claim 1, wherein the shell is divided in a length direction to an isolated shell section and a shell section connected to a body of the connector whereby performing a divided section. ### Claim 7 (depends on 1) The coupler according to claim 1, wherein at least one part of the shell is connected to ground and another part of the shell is connected to the substrate. ### Claim 8 (depends on 1) The coupler according to claim 1, wherein the central conductor is connected to one of the dividing ports on the substrate. ### Claim 9 (depends on 1) The coupler according to claim 1, wherein at least one of the resistive elements are arranged circularly with respect to the central conductor of the connector and/or wherein at least one of the resistive elements is formed as at least one segment of a circle with respect to the central conductor. ### Claim 10 (depends on 1) The coupler according to claim 1, wherein the connector is placed in a recess area of the substrate. ### Claim 11 (depends on 1) The coupler according to claim 1, wherein at least one ferrite-bead is arranged on or around the connector. ### Claim 12 (depends on 11) The coupler according to claim 11, wherein the substrate comprises a recess area configured to receive at least one of the ferrite-beads and/or wherein the connector comprises a circular slot adapted to integrate at least one of the ferrite-beads. ### Claim 13 (depends on 11) The coupler according to claim 11, wherein the at least one ferrite-beads is penetrated by the central conductor of the connector and by the shell conductor of the connector.
