E6E04
Which is the most common input and output impedance of MMICs?
- A.50 ohms (correct answer)
- B.300 ohms
- C.450 ohms
- D.75 ohms
Why50 ohms is the most common input and output impedance of MMICs. MMICs are most commonly designed with 50 ohm input and output impedance, matching the standard impedance used throughout most RF systems and test equipment, which makes cascading and interconnecting them straightforward, answer A. 300, 450, and 75 ohms are impedances associated with other applications (like antenna feed lines or video), not the typical MMIC design standard.
