Which of the following materials supports the highest frequency of operation when used in MMICs?
The correct answer is D: Gallium nitride. Which of the following materials supports the highest frequency of operation when used in MMICs is gallium nitride. GaN supports the highest frequencies in MMICs. For amateur radio operators, this is important for semiconductor knowledge. Understanding this helps when selecting MMIC materials.
Exam Tip
Highest frequency MMIC material = gallium nitride. Think 'G'allium 'N'itride = 'G'reatest 'N'ext-generation (highest frequency). GaN supports the highest frequencies in MMICs. Not silicon, not silicon nitride, not silicon dioxide - just gallium nitride.
Memory Aid
"Highest frequency MMIC material = gallium nitride. Think 'G'allium 'N'itride = 'H'ighest frequency. GaN supports the highest frequencies in MMICs. Important for semiconductor knowledge."
Real-World Application
Materials used in MMICs: Gallium nitride supports the highest frequency of operation. GaN has excellent high-frequency properties, making it ideal for microwave MMICs. This is the material - gallium nitride for highest frequency.
Key Concepts
Why Other Options Are Wrong
Option A (Silicon): Incorrect. Silicon doesn't support highest frequency - gallium nitride does. Silicon isn't the material.
Option B (Silicon nitride): Incorrect. Silicon nitride doesn't support highest frequency - gallium nitride does. Silicon nitride isn't the material.
Option C (Silicon dioxide): Incorrect. Silicon dioxide doesn't support highest frequency - gallium nitride does. Silicon dioxide isn't the material.
