Hi :)

Does anyone know a single device that fulfills the following functionality? Unidirectional signal from top to bottom: At first two signals need to be coupled together. The result is then splitted into two branches.

It's Combiner-Splitter Combination, not Coupler..
If you attempt to combine 2 signals then divide these signals into 2 branches, you have to design a Wilkinson Combiner/Divider in a Cascade Configuration.Combiners are different.

I think that you want from this structure to have directivity, so a coupler is mandatory to be used.
I never seen these two components (coupler and splitter) in the same package. Should be possible to exist this device, but I never saw it.

Thank you for your anwers.

Meanwhile: the first component is required to be a coupler. Signal drop of -20 dB is accepted. So I design my RF chain to have a -20 dB coupler and afterwards a power splitter.

Both components (coupler and splitter) can be designed on a PCB layout.
Depending by the design, and by the PCB properties, can be reached high frequency range.
Most of the commercial RF/EM simulators have models for couplers and splitters, which makes the project easier to be done.

Thank you vfone. I know that it is possible to design it myself (and I am capable of doing it), but I was questioning whether there are already such components on the market.
