Abstract

A coupler, in particular a resistive coupler, wherein all ports are at least partially or completely arranged in or at a connector. 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.

First claim

What is claimed is:

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.

2. The coupler according to claim 1 ,
wherein the resistors are ceramic resistors and/or
wherein at least two resistors comprise a common ceramic substrate.

3. The coupler according to claim 2 ,
wherein the common ceramic substrate is arranged within a divided section of the shell.

4. The coupler according to claim 2 ,
wherein the common ceramic substrate is penetrated by the central conductor of the connector.

5. The coupler according to claim 1 ,
wherein at least one of the resistors comprises a thin-film resistive element.

6. 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.

7. 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.

8. The coupler according to claim 1 ,
wherein the central conductor is connected to one of the dividing ports on the substrate.

9. 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.

10. The coupler according to claim 1 ,
wherein the connector is placed in a recess area of the substrate.

11. The coupler according to claim 1 , wherein at least one ferrite-bead is arranged on or around the connector.

12. 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.

13. 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.
