Device for generating IQ signals and method for manufacturing a device for generating IQ signal

A method for manufacturing a device for generating IQ signals, comprising the following steps:

• forming an input port that is configured to receive a differential input signal via a first and a second terminal of the input port;
• forming a first output port that is configured to output a differential I output signal via a first and a second terminal of the first output port, wherein the first terminal of the input port is electrically connected to the first terminal of the first output port via a first connecting line, and the second terminal of the input port is electrically connected to the second terminal of the first output port via a second connecting line;
• forming a second output port that is configured to output a differential Q output signal via a first and a second terminal of the second output port;
• and
• forming an isolated port having two terminals, wherein the first terminal of the second output port is electrically connected to a first terminal of the isolated port via a third connecting line, and the second terminal of the second output port is electrically connected to a second terminal of the isolated port via a fourth connecting line;
• wherein the first and second connecting lines are formed in at least a first plane of a substrate of the device, and the third and fourth connecting lines are formed offset to the first and second connecting lines in at least a second plane of the substrate;
• and
• wherein the first, second, third, and fourth connecting lines are arranged symmetrically with respect to a first axis and asymmetrically with respect to a second axis in a top view, wherein the first axis and the second axis are orthogonal to one another in a substrate plane of the substrate.
