NRF21540

[Berkay Dudu]

Hello,

can 2.0nH or 1.8nH inductors be connected instead of the 1.9nH inductors connected to the ANT1 and ANT2 pins shown in the NRF21540 reference circuit?

Your schematic is out of date, please see the latest at https://docs.nordicsemi.com/bundle/ps_nrf21540/page/chapters/hw_layout/reference_circuitry/doc/alt2.html

All component needs to be at the specified value. If you need to change it, you have to check that the filtering of the harmonics is still ok.
