I am currently developing an RF system whereby I want to use the nRF24L01 transceiver, although I'm quite new to RF design and the various intricacies that come with it. I am aware most circuits tend to match towards 50 ohms, what a smiths chart and the basic theory, but the only thing stopping me from accurately designing this circuit is how to figure out the source impedance of the ANT pins primarily. I know an easy solution would be to use the example circuit but I want to know why the various inductor and capacitor values were chosen, how its configuration in relation to the source and load impedance affects impedance and such. The data sheet of this transceiver only mentions the load impedance for maximum power output of (15 + j88) ohms, but no mention of the source impedance for the necessary pin. I simply just need insight from someone more experienced than myself so I can gain a more profound understanding.
