SMA coaxial RF connector is a commonly used RF connector, usually used to connect cables and equipment for RF signals.
The SMA coaxial RF connector is characterized by its small size and light weight, suitable for narrow bandwidth, and the interface impedance is 50Ω. The contact method of the SMA coaxial RF connector is an internal contact type, in which the conductor of the cable is in close contact with the contact surface of the connector.
SMA coaxial RF connectors are usually used in RF signal transmission systems, such as RF testers, radio communication equipment, radar equipment, etc.
SMA coaxial RF connectors have good RF performance, including bandwidth, impedance matching, insertion loss, durability and other properties.
1. Bandwidth: The bandwidth of SMA coaxial RF connectors is narrow, usually between several hundred MHz and several GHz.
2. Impedance matching: The interface impedance of the SMA coaxial RF connector is 50Ω, so it can be well matched with the 50Ω line impedance.
3. Insertion loss: The insertion loss of SMA coaxial RF connectors is generally around 0.1dB, which is relatively low.
4. Durability: SMA coaxial RF connectors have better durability and can withstand more plugging times, usually more than thousands of times.
SMA coaxial RF connector technology
1. Material preparation: Prepare the materials of each part of the connector, including metal plating, contact body, sealing ring, etc.
2. Forming: According to the design drawings of the connector, use molds or processing equipment to form the material into various parts of the connector.
3. Plating: Plating is applied to each part of the connector, and various methods such as electroplating, passivation, etc. are used for plating.
4. Assembly: Assemble the various parts of the connector together to form a complete connector.
5. Testing: Perform various performance tests on the completed connectors to ensure the quality of the connectors.
6. Packaging: Packaging the completed connectors, ready for sale or use.
