Extra exam question E6E06

What characteristics of MMICs make them a popular choice for VHF through microwave circuits?
- A.The ability to retrieve information from a single signal, even in the presence of other strong signals
- B.Extremely high Q factor and high stability over a wide temperature range
- C.Nearly infinite gain, very high input impedance, and very low output impedance
- D.Controlled gain, low noise figure, and constant input and output impedance over the specified frequency range (correct answer)
WhyMMICs are popular for VHF through microwave circuits because of their controlled gain, low noise figure, and constant input and output impedance over their specified frequency range. MMICs are popular for VHF through microwave circuits because they offer controlled, predictable gain, a low noise figure, and input and output impedances that stay reasonably constant across their specified frequency range, all packaged in a small, easy-to-use device, answer D. Interference rejection in the presence of strong signals, extremely high Q and temperature stability, and near-infinite gain with mismatched high/low impedances aren't accurate descriptions of what makes MMICs broadly useful.
