1. For RF OUT port, it is ac couple or dc couple??
Datasheet page8 showed the RF OUT is ac couple. But in functional diagram, RF OUT seemed to be dc couple.
2. RF IN is dc couple and if need to add a external capacitor to block the DC, what kind of capacitor (package, value and part number) will you suggest??
We call this DC coupled because there are shunt resistors to ground but this device is AC coupled at input and output therefore there is no need for external capacitors.
Thanks for your reply.
But if previous or next stage is a DC coupled device, so need a capacitor to block DC.
Is that rignt?
Besides, our operating frequency is at 7.56GHz and component performance is sensitive to external lumped elements.
So, if need to add an external DC block capacitor, what will you suggest??
