Features:
- High Reliability: - The ability to work stably under extreme temperature, humidity, vibration, shock and other harsh environments ensures that the connector can still maintain good connection performance under the various complex conditions of spacecraft in space. For example, some aerospace-grade SMA connectors can withstand temperatures ranging from -55°C to 125°C, and can withstand high acceleration and strong vibration shocks. - Good corrosion resistance to cope with corrosive substances or environments that may exist in space, extending the service life of the connectors.
- Precise Mechanical Structure: - The precise structural design ensures that the threaded connection of the connector is tight and reliable, preventing loosening under vibration or shock conditions. Meanwhile, the connector pins and jacks are machined with high precision to ensure good electrical contact. - With certain mechanical strength, they can withstand the mechanical stress during installation and use and are not easily damaged.
- Strict Quality Control and Inspection: - The production process follows a strict quality management system, and each production step is strictly inspected and controlled to ensure that the quality and performance of the products meet the aerospace standards. For example, the electrical performance, mechanical performance and environmental adaptability of the connectors will be thoroughly tested and verified. - A series of reliability tests, such as temperature cycling test, thermal vacuum test, vibration test, mechanical shock test, etc., will be carried out before leaving the factory to simulate the space environment to evaluate the connectors.
Application:
- Spacecraft communication system:
- Signal transmission connection: in the communication system of spacecraft such as satellites, SMA connectors are used to connect various RF cables and equipment to ensure stable signal transmission. For example, in the communication link between the satellite and the ground station, the SMA connector connects RF transceiver modules, filters, amplifiers and other key equipment to ensure normal communication.
- Antenna system connection: the antenna system of the spacecraft needs to be connected with the internal RF signal processing equipment, and the SMA connector can provide a reliable connection to ensure that the signals received by the antenna can be accurately transmitted to the subsequent processing circuit.
- Aerospace measurement and control system:
- Measurement and control equipment connection: in the ground measurement and control station equipment, SMA connectors can be used to connect radar, telemetry equipment and so on. These equipments need RF connection with antennas, signal processing equipments, etc. to realize the tracking, measurement and control of spacecraft.
- Data transmission link: The data transmission link within the measurement and control system also needs to use SMA connectors to connect different modules and devices to ensure real-time and accurate transmission of measurement and control data.
