Question
What is an SMA connector?
Answer Options
- A) A type-S to type-M adaptor
- B) A small threaded connector suitable for signals up to several GHz
- C) A connector designed for serial multiple access signals
- D) A type of push-on connector intended for high-voltage applications
Correct Answer: B
Explanation
The SMA (SubMiniature version A) connector is a widely used coaxial RF connector, notable for its very small size. It features a locking, threaded coupling mechanism which ensures a stable and reliable connection, even at high frequencies.
The SMA is a small threaded connector suitable for signals up to several \text{GHz} (often up to 18-26 \text{ GHz} on high-quality versions). It is predominantly used on internal circuitry, small antenna connections, and precision test equipment due to its excellent electrical performance at microwave frequencies.
