Bochuang SpaceTime's standard SMA RF coaxial connector is engineered for high-frequency signal transmission, serving as an essential component in wireless communication devices. This product strictly adheres to the 50Ω impedance standard. Its center pin is crafted from high-purity copper with a thickened gold plating to minimize contact resistance and prevent oxidation, ensuring low-loss signal transmission across the 2.4GHz/5.8GHz bands (WiFi, Bluetooth, Zigbee) and in 4G LTE applications. Its unique threaded locking mechanism delivers superior mechanical stability, resisting vibration and loosening—making it ideal for environments subject to movement, such as vehicle-mounted radios, industrial routers, and outdoor base stations. Whether replacing damaged connectors, extending antenna feed lines, or assembling custom RF test cables, this connector provides military-grade reliability. It is compatible with the vast majority of standard SMA interfaces found on routers, network cards, and communication modules.

Core Advantages & Technical Highlights:

50Ω precision impedance matching for low-loss transmission:
Engineered to strict 50Ω RF standards, ensuring optimal performance across a DC-6GHz frequency range that fully covers 2.4G/5.8G WiFi, Bluetooth, Zigbee, 4G LTE, and other mainstream bands.
) achieves an extremely low voltage standing wave ratio (VSWR). With virtually no signal reflection or attenuation during transmission, it ensures optimal device performance.
Thickened gold-plated contacts for oxidation and corrosion resistance:
The center conductor is made of high-purity copper with a thick gold-plated surface. Unlike standard nickel-plated products, the gold plating effectively prevents degradation from long-term air exposure.
oxidized to a black finish, significantly reducing contact resistance. Even in harsh environments such as high humidity or salt fog, it maintains excellent conductivity and withstands thousands of repeated cycles.
Plug and play.
Thread-locking design for vibration resistance and anti-loosening:
Using a classic threaded coupling mechanism, SMA connectors provide a far more secure mechanical connection than push-on interfaces—ideal for automotive communications, drone operations, and industrial applications.
In vibrating environments, prevents loose contacts or accidental disconnection due to shaking, ensuring uninterrupted signal transmission.
All-metal shielded enclosure with strong anti-interference performance:
Crafted from premium brass via precision machining for durability. The all-metal enclosure provides effective electromagnetic interference (EMI) shielding to block external noise.
Minimizes interference to ensure signal purity and stability.
Broadly compatible, plug and play:
Fully compatible with the vast majority of standard SMA interface devices on the market, including wireless routers, 4G/5G CPE modules, GPS trackers, FPV drone video transmitters, and handheld units.
Walkie-talkies and various RF test instruments. No soldering required for seamless device interconnection.
