Copper Alloy Female/Jack 2 Hole Flange Mount SMA RF Connector Up To 18GHz
Product Description
The SMA RF connector is an extremely widely used small threaded RF coaxial connector. It can be found in a variety of communication equipment and test instruments.
Core Features:
1) Compact Size, Space-Saving
As an ultra-miniature connector, the SMA RF connector is approximately half the size of a traditional N-type connector (about 1/5 of its volume) and extremely light in weight. This makes it ideal for use in electronic devices with compact spaces and high-density wiring requirements, such as PCBs, micro-modules, and portable instruments.
2) Wide Frequency Range, Excellent Performance
This is one of the biggest advantages of the SMA RF connector. It features an extremely wide operating frequency range, usually up to 0 - 18 GHz, and some high-quality or specially designed models can even extend to 26.5 GHz. It can effectively reduce reflection and loss during high-frequency signal transmission, ensuring signal integrity.
3) High Reliability for the Connection
Different from the bayonet connection of BNC connectors, the SMA RF connector adopts a threaded locking mechanism. This design ensures a very firm connection, with excellent vibration and impact resistance, which can effectively prevent accidental loosening in harsh environments and guarantee long-term connection stability.
