I am trying to use a differential antenna with the NRF51422 and I do not want to misunderstand the datasheet. It says that the optimum differential impedance at 2.4 GHz seen into the matching network from pin ANT1 and ANT2 is 15+85j Ohms so I understand the differential impedance of the port into the chip is 15-85j.
Could you please tell me if I am right?
Thank you in advance.
