How is power supplied to the most common type of MMIC?
- A.Through a capacitor and RF choke connected to the amplifier input lead
- B.MMICs require no operating bias
- C.Through a resistor and/or RF choke connected to the amplifier output lead (correct answer)
- D.Directly to the bias voltage (Vcc) lead
WhyPower is supplied to the most common type of MMIC through a resistor and/or RF choke connected to the amplifier's output lead. Power is most commonly supplied to an MMIC through a resistor and/or RF choke connected to the same lead that carries the amplifier's RF output, letting DC bias and RF signal share a single pin without a separate dedicated bias lead, answer C. It isn't fed through the input lead, MMICs do require operating bias (they're active amplifying devices), and it isn't simply wired directly to a separate Vcc lead, most common MMICs use this combined output-lead biasing scheme instead.
