As the seller correctly stated this is a balun. So, in reply to one of the other buyers, if you attach 50 Ohm to port 2 and 3, one sees 100 Ohm on port 1. That is normal and the swr is then equal to 2 as you can see on the VNA. You also have no isolation between port 2 and 3. If you want that and if you want 50 Ohm visible on port 1, you need a hybrid. You can do that with this module: You have to rewind the transformer according to the picture and add 25 Ohm to GND as shown. Using 5 winding on one side and two times 3 windings on the other side give you excellent isolation and about 3.5dB insertion loss. The nice thing is that the transformer has an island for a middle tap and place on the PCB to add two 50 Ohm SMD resistors in parallel. Maybe the seller can ask his supplier to modify the module like that, because the demand for a real hybrid is high.
