What advantage does surface-mount technology offer at RF compared to using through-hole components?
The correct answer is D: All these choices are correct. What advantage does surface-mount technology offer at RF compared to using through-hole components includes: smaller circuit area, shorter circuit board traces, and components have less parasitic inductance and capacitance. All three are advantages. For amateur radio operators, this is important for RF circuit design. Understanding this helps when selecting components.
Exam Tip
All three are advantages of surface-mount at RF: smaller area, shorter traces, less parasitics. When all listed advantages are valid, 'all of the above' is usually the answer. All are valid advantages.
Memory Aid
"All three are advantages of surface-mount at RF: Smaller area, Shorter traces, Less parasitics. Think 'A'll 'S'urface-'M'ount advantages. All three are valid advantages. Important for RF circuit design."
Real-World Application
