Features:
- High Reliability: Aerospace RF coaxial connectors need to meet harsh environmental requirements such as low temperature, high temperature, vacuum, radiation, etc.. These connectors must be able to withstand extreme temperature changes and vacuum environments, while maintaining stable performance in strong radiation environments.
- High performance: Aerospace grade RF coaxial connectors typically have excellent mechanical, electrical and environmental properties. This means they maintain good signal integrity and low loss in high frequency transmissions.
- Precision Design: The design of aerospace RF coaxial connectors requires consideration of a variety of factors, including structural design, reliability design, and realization process. For example, to improve its inherent reliability, the design will take measures from the thermal design, corrosion prevention, aging design.
Application:
- Communication systems: Aerospace vehicles require real-time data transmission with ground stations, which requires connectors that can maintain stable signal transmission in extreme environments. Aerospace-grade RF coaxial connectors ensure signal integrity and low loss, which are critical to maintaining spacecraft communications.
- Navigation systems: The positioning and navigation systems of spacecraft require extreme accuracy, and any small signal interference can lead to navigation errors. Aerospace-grade RF coaxial connectors help minimize signal interference and improve the accuracy of navigation systems through their superior electrical performance.
