Hi,
I want to implement a currently existing antenna to TRF7970A. Here is the datasheet of the antenna that I will use.
But the recommended EMC filter circuit in the antenna datasheet is different with the one in the datasheet of TRF7970A (P.15, Figure 4-2. Application Schematic – SPI With SS Mode MCU Interface)
May I keep the EMF filter in the datasheet of TRF7970A but not using the recommended EMC filter circuit in the antenna datasheet?
Also, as there is only one TX pin in TPF7970A only but there are two TX pins in the antenna datasheet. Is it a problem if I connect TX2 to ground?
Thank you for the help!
