*Question E6E08:
How is power supplied to the most common type of MMIC?*  

*Correct Answer is  C: Through a resistor and/or RF choke connected to the amplifier output lead*  

### AI Response: (may contain errors)  

To understand how power is supplied to the most common type of Monolithic Microwave Integrated Circuit (MMIC), let's analyze the correct answer and the other options.

### Correct Answer: 
**D: Directly to the bias voltage (Vcc) lead**

- **Explanation**: MMICs typically require a DC bias voltage to operate, which is supplied directly to the bias voltage lead (often labeled as Vcc). This voltage is essential for the active devices within the MMIC to function properly, allowing them to amplify RF signals.

### Why the Other Choices are Incorrect:

- **A: Through a capacitor and RF choke connected to the amplifier input lead**  
  - **Explanation**: This option suggests that power is supplied at the input, which is not correct. The input is meant for RF signals, not for DC power. Capacitors and RF chokes are used for AC coupling and filtering, not for supplying power.

- **B: MMICs require no operating bias**  
  - **Explanation**: This statement is false. Most MMICs do require a bias voltage to operate effectively. Without this bias, the MMIC would not function as intended.

- **C: Through a resistor and/or RF choke connected to the amplifier output lead**  
  - **Explanation**: This option is misleading. While RF chokes can be used in the output stage for impedance matching or filtering, they are not the primary means of supplying power. The power is supplied directly to the Vcc lead, not through the output.

### Summary:
- MMICs need a DC bias voltage supplied directly to the Vcc lead for proper operation.
- The other options either misplace the power supply connection or incorrectly state the requirements of MMICs.

### Useful Rule of Thumb:
- Always remember that MMICs require a DC bias voltage for operation, typically supplied at the designated Vcc lead, while RF chokes and capacitors are used for signal coupling and filtering, not for power supply.
