🔍 Key Concepts

• Q (quality factor) of an inductor or transformer and what a higher Q physically means in RF circuits • How selectivity in a tuned RF circuit relates to bandwidth and Q • How special iron (ferrite) cores affect inductance, losses, and circuit gain at radio frequencies

💭 Think About

• Think about how using a specially designed iron core changes the magnetic properties of the inductor: does it tend to reduce losses, increase inductance, or both? • Ask yourself how changes in Q will affect the sharpness (narrowness) of tuning – and how that relates to selectivity. • Consider whether improved core materials and construction can realistically affect just one of these parameters (Q, gain, selectivity), or if multiple of them are influenced together.

✅ Before You Answer

• Review the relationship: higher Q ⇒ narrower bandwidth ⇒ higher selectivity in tuned RF circuits. • Check how core losses (hysteresis and eddy currents) in iron vs air cores affect both Q and circuit gain. • Verify whether RF transformers with special cores are specifically used to improve Q, selectivity, and/or gain, and whether any one of the listed benefits is independent of the others.
