Hi everyone,
I am working on an RFID project.
Therefor I was studying an RFID reader module.
But I cannot find a specific part.
In the picture there are 2 SMD housings with 8 pins.
The upper one, is an low pass filter.
But the lower one remains unknown.
If i look at the traces it should be an directional coupler.
But i cant find a coupler in this 8 pin housing.
Is there someone who knows what this component is?
