Features:
1. High Reliability: - Stable operation under extreme temperature, humidity, vibration, shock and other harsh environments ensures that the connector can still maintain good connection performance under the 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.
2. Lightweight design: - On the premise of meeting the performance requirements, the weight of the connector is reduced as much as possible to lower the total weight of the spacecraft and improve the launch efficiency and operational performance of the spacecraft. For example, adopting lightweight materials or optimizing structural design to achieve lightweighting.
Application:
1. Spacecraft communication system:
Signal transmission connection: In the communication system of satellites and other spacecraft, SMA connectors are used to connect various RF cables and equipment to ensure stable signal transmission. For example, in the communication link between satellites and ground stations, SMA connectors connect key equipment such as RF transceiver modules, filters, and amplifiers to ensure normal communication.
2. Antenna system connection: The antenna system of the spacecraft needs to be connected to the internal RF signal processing equipment. SMA connectors can provide reliable connections to ensure that the signals received by the antenna can be accurately transmitted to subsequent processing circuits.
