Selection guidelines
1. Common Adapter Cable Specifications and Characteristics
model | external dia- meter | center condu- ctor | 3GHz loss | characteristic | applicable scene |
RG-174 | 2.8mm | 7*0.16mm | 0.82dB/m | Flexible, easy to inst- all, low cost | CE |
RG-316 | 2.6mm | 7*0.1mm | 0.84dB/m | High temperature resistance, military standard | High temperature environment, test instrument |
Microfoamed PE wire | 1.5~2.2mm | 0.3~0.5mm | 0.50dB/m | Low loss at high fr- equency | 5G/Wi-Fi |
Semi-wire | 1.0~3.0mm | Solid copper | 0.30dB/m | Relatively stable and shielded well | Test calibration, millimeter wave front end |
2. Key Parameter Comparison and Selection Logic
2.1 Electrical performance priority
parameter | RG-174 | RG-316 | Foamed PE line | influence |
damping @6GHz | 1.8dBm/m | 1.7dBm/m | 0.9dBm/m | High frequency signal integrity |
screening effectiveness | 70dB | 90dB | >90dB | capacity of resisting disturbance |
impedance stability | ±3Ω | ±2Ω | ± 1Ω | Reflection signal suppression |
2.2. Mechanical and environmental adaptability
parameter | RG-174 | RG-316 | Foamed PE line |
minimum bending radius | 15mm | 25mm | 30mm |
Temperature tolerance range | -40℃ ~ +85℃ | -65℃ ~ +200℃ | -50℃ ~ +85 ℃ |
tensile strength | secondary | tall | Low (easily damaged) |
3. Typical Application Scenarios and Cable Ma-
tching
3. 1 Consumer electronics (Bluetooth/Wi-Fi) cable: RG
-174
Reasons: cost sensitive, frequency ≤ 5GHz, short length ( <0.3m) and controllable loss.
3. 2 test instrument jumper (vector network analyzer)
Cable: RG-316 or low-loss foam cable (e.g. Times LMR-200)
Reason: It needs to be resistant to plug and pull, low loss (high calibration accuracy).
3.3. Car-mounted radar /5G small base station
Cables: PTFE insulated foam lines (e.g. Gore G- FLEX 150)
Reason: 6 ~ 24GHz low loss requirement, outer diameter ≤2 mm for wiring.
3.4 Military equipment
Cable: RG-316 (Military standard MIL-DTL-17)
Reason: Extreme temperature, vibration, high shielding requirements.
4.Supplementary Specification
4. 1. Outer diameter mismatch: MCX connector usually supports wire diameter of 1.0 ~ 3.0mm, and customization is required beyond the range (e.g., special MCX head is required for miniature wire).
4. 2 High frequency loss: The loss of RG-174 at 6 GHz is twice as high as that of foamed PE wire, so it should not be used for long distance transmis- sion.
4. 3-phase stability: Phase sensitive applications (phase array) are preferred semi-rigid lines or phase-stabilized cables (e.g. Huber+Suhner S 100).
4.4 connector class: Select gold plated contact MCX (non-nickel plated) to ensure a life of more than 500 pluggings and unplugs.
