How did you get to your answer 2 x 49.2pF capacitors? Are you assuming 0 for Cp and Cint? I got 98.4 pF per capacitor, 196.8 pF total. I’m thinking one of us has dropped a 1/2 somewhere. Are you using the equations from the nrf52480 data sheet? Sorry to be a pain just want to be right before I order them!! Other than that, thanks for everything. I’ll try again with the capacitors and let you know how it goes! One last thing, when you say you got 3 inches range, which antenna is that with??
