Question
What is meant by the term MMIC?
Answer Options
- A) Multi-Mode Integrated Circuit
- B) Monolithic Microwave Integrated Circuit
- C) Metal Monolayer Integrated Circuit
- D) Mode Modulated Integrated Circuit
Correct Answer: B
Explanation
MMIC is an acronym that stands for Monolithic Microwave Integrated Circuit. These are specialized Integrated Circuits (ICs) designed to operate at extremely high frequencies, typically in the microwave and millimeter wave regions (above 1 \text{ GHz}).
MMICs integrate all necessary components, such as transistors, resistors, capacitors, and even transmission lines, onto a single semiconductor chip. They are commonly used in the front-end amplifier stages of transceivers because they provide high gain and a very low noise figure across a wide range of high frequencies.
