What type of transmission line is often used for connections to MMICs?
The correct answer is D: Microstrip. What type of transmission line is often used for connections to MMICs is microstrip. Microstrip is commonly used with MMICs. For amateur radio operators, this is important for RF circuit design. Understanding this helps when connecting to MMICs.
Exam Tip
Transmission line for MMICs = microstrip. Think 'M'MIC = 'M'icrostrip. Microstrip is commonly used with MMICs. Not miniature coax, not circular waveguide, not parallel wire - just microstrip.
Memory Aid
"Transmission line for MMICs = microstrip. Think 'M'MIC = 'M'icrostrip. Microstrip is commonly used with MMICs. Important for RF circuit design."
Real-World Application
Connections to MMICs: Microstrip transmission line is often used. Microstrip is easy to fabricate on PCBs and works well with MMICs. This is the type - microstrip for MMIC connections.
