How is power supplied to the most common type of MMIC?
Pick an answer to check it.
Answer: C. Through a resistor and/or RF choke connected to the amplifier output lead
Common MMICs get DC power through a resistor and/or RF choke connected to the output lead. The choke passes DC while keeping RF out of the power supply.
Tip: MMIC power feeds in through the output.
