I am designing an RF transciever board. I have quite a few inductors in the RF section. But, I am a novice in RF circuits and hence am not so aware of the parameters of importance. My usage of inductors is for switching power circuits and I usually just check the DCR and the saturation current. Then based on the formula for inductance I select it.
But, when it comes to RF inductors, how do I select them ? I have read that there are 2 more parameters viz - Q factor and SFR. The Q factor , I understand is Q = Xl/Rl i.e - Impedance of the Inductance/Resistive component of Inductance.
Now, what is the SFR ? I find confusing definitions online. I would appreciate if anyone could point me to a tutorial on this please.
Also, how does the Q factor and SFR affect the performance of the circuit ?
