Web17 nov. 2024 · A Smith chart is developed by examining the load where the impedance must be matched. Instead of considering its impedance directly, you express its reflection coefficient Γ L, which is used to characterize a load (such as admittance, gain, and transconductance). The Γ L is more useful when dealing with RF frequencies.
