In the schematic diagram of adfmcomms1 ebz there is a unbalanced to balanced converter shown named T9. But on the hardware there is no such component available.can anyone tell something about this??
The "DNI" means "Do not insert".
The T6/T9 baluns are tuned for different frequencies - and only one is to be inserted at one time. To ensure this happens - the footprints of the 2 parts are overlaid (take up the same space). That is why the footprint for T6 seems too big - it's a combo which can accept either part.
