Which of the following describes a type N connector?

  1. An RF connector limited to 1 GHz

  2. A moisture-resistant RF connector useful to 10 GHz

  3. A connector used exclusively for audio signals

  4. A connector designed for high voltage applications

The correct answer is: A moisture-resistant RF connector useful to 10 GHz

A type N connector is specifically designed to operate effectively at microwave frequencies, making it a suitable choice for applications up to 10 GHz. One of its significant features is its moisture-resistant design. This characteristic allows it to maintain performance in outdoor conditions, which is particularly important for communication systems that may be exposed to various environmental factors. This connector type typically has a robust mechanical structure that ensures a reliable connection and minimizes signal loss, making it ideal for high-frequency RF applications. Its durability and performance in challenging conditions further solidify its usefulness in a variety of telecommunications and radio frequency applications. Options describing a connector limited to 1 GHz, used exclusively for audio signals, or designed for high voltage applications do not accurately represent the functionalities and specifications of a type N connector, as these connectors are distinctly different in purpose and application.
