What advantage does surface-mount technology offer at RF compared to using through-hole components?
Smaller circuit area
Shorter circuit board traces
Components have less parasitic inductance and capacitance
All these choices are correct✓Bonne réponse
Explication
Surface-mount parts are physically smaller, which shrinks the board area and in turn shortens the traces between components, and their negligible leads cut parasitic inductance and capacitance. All three are genuine RF advantages, so the combined answer is the correct one.
