Features:
- Good corrosion resistance: These connectors have good corrosion resistance and can cope with corrosive substances or environments that may exist in space, thus extending their service life.
- Lightweight design: The weight of aerospace-grade SMA connectors is minimized as much as possible while meeting performance requirements to reduce the overall weight of the spacecraft, thereby improving launch efficiency and operational performance. This is often achieved through the use of lightweight materials or optimized structural design.
- Miniaturization and High Frequency Characteristics: SMA connectors are widely used in aerospace-grade products due to their miniaturization, high frequency and high performance characteristics. They are capable of stable operation in the transmission frequency range up to 18 GHz or higher.
Application:
- Spacecraft Communication System:Signal Transmission Connection: In the communication systems of satellites and other spacecraft, SMA connectors are utilized to link various RF cables and equipment, ensuring stable signal transmission. For instance, in the communication link between satellites and ground stations, SMA connectors connect essential equipment such as RF transceiver modules, filters, and amplifiers to ensure proper communication.
- 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.
