I. Connector type and cable specifications
SMA adapter type
Male-female conversion: Support SMA male (external thread) to female (internal thread), such as SMA-J (male) to SMA-K (female), to meet the port matching requirements of different devices.
Cross-model conversion: Compatible with SMA to MCX, SMB, MMCX and other interfaces, such as SMA female to MCX male elbow cable (elbow design saves space).

RG316 coaxial cable characteristics
Material and structure: Adopt 50Ω impedance coaxial cable, copper core conductor + polytetrafluoroethylene (PTFE) insulation layer, outer layer wrapped with tinned copper braided shielding layer, strong anti-interference ability26.
Electrical performance: Frequency coverage DC-6GHz, standing wave ratio ≤1.20:1, suitable for high-frequency signal transmission.
2. Application scenarios and selection recommendations
High-frequency signal transmission scenarios
Communication equipment : used for jumper connections in scenarios such as base stations and RF modules, with low loss and high stability .
Test instruments : used as standard test lines in conjunction with spectrum analyzers, network analyzers and other equipment .
Length and configuration selection Regular length : 10cm, 1m, 5m, 10m and other specifications are provided. Short distances (≤1m) are suitable for in-machine wiring, and long distances (≥5m) are used for inter-device connections .
Customized service : support adjustment of cable length, connector angle (straight/bent) and sheath material (such as high-temperature resistant PVC or PU) as required .
3. Technical parameters and performance requirements Mechanical and environmental adaptability Durability : plug-in life ≥500 times, operating temperature range -45℃~125℃, suitable for harsh environments .
Protective design: UV-proof sleeves are required for outdoor use, and waterproof junction boxes are optional for humid environments.
Installation precautions
Avoid excessive bending: The bending radius should be ≥5 times the cable diameter to prevent the shielding layer from breaking and causing signal attenuation.
Spacing control: Maintain a parallel spacing of ≥50cm with the strong power line, and vertically isolate when crossing to reduce interference.
IV. Supplier and procurement reference
Mainstream suppliers
