What characteristics of MMICs make them a popular choice for VHF through microwave circuits?
The ability to retrieve information from a single signal, even in the presence of other strong signals
Extremely high Q factor and high stability over a wide temperature range
Nearly infinite gain, very high input impedance, and very low output impedance
Controlled gain, low noise figure, and constant input and output impedance over the specified frequency range✓Bonne réponse
Explication
MMICs are popular because they arrive with gain, noise figure, and 50-ohm input and output impedance already specified across a stated frequency range, so a builder gets predictable results without designing matching networks. Selectivity among strong signals, extremely high Q, and near-infinite gain describe receivers, resonators, and op-amps rather than MMICs.
