How is power supplied to the most common type of MMIC?
The correct answer is C: Through a resistor and/or RF choke connected to the amplifier output lead. How is power supplied to the most common type of MMIC is through a resistor and/or RF choke connected to the amplifier output lead. MMICs typically receive power through the output lead. For amateur radio operators, this is important for MMIC operation. Understanding this helps when powering MMICs.
Exam Tip
MMIC power supply = through resistor and/or RF choke on amplifier output lead. Think 'M'MIC 'P'ower = 'O'utput 'L'ead. MMICs typically receive power through the output lead. Not input lead, not no bias, not direct Vcc - just through output lead.
Memory Aid
"MMIC power supply = through resistor and/or RF choke on amplifier output lead. Think 'M'MIC 'P'ower = 'O'utput. MMICs typically receive power through the output lead. Important for MMIC operation."
Real-World Application
Powering the most common type of MMIC: Power is supplied through a resistor and/or RF choke connected to the amplifier output lead. The RF choke blocks RF while passing DC. This is how power is supplied - through output lead.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Through capacitor and RF choke on input lead isn't correct - power is supplied through output lead. Input lead isn't correct.
Option B: Incorrect. MMICs requiring no operating bias isn't correct - MMICs need bias, supplied through output lead. No bias isn't correct.
Option D: Incorrect. Directly to Vcc lead isn't correct - most MMICs don't have separate Vcc lead, power is through output lead. Direct Vcc isn't correct.
