| Selection guide | |||||
| 1. Commonly used adaptive cable specifications and characteristics | |||||
| Model | Outside diameter | Central conductor | 3GHz loss | Distinguishing feature | Applicable scenarios |
| RG-174 | 2.8mm | 7*0.16mm | 0.82dB/m | Flexible, easy to install, low cost | Consumer electronics |
| RG-316 | 2.6mm | 7*0.1mm | 0.84dB/m | High temperature resistance, military industry standards | High-temperature environment, test instruments |
| Micro-foam PE line | 1.5~2.2mm | 0.3~0.5mm | 0.50dB/m | Low high-frequency loss | 5G/Wi-Fi |
| Semi-steel wire | 1.0~3.0mm | Solid copper | 0.30dB/m | Relatively stable and well shielded | Test calibration, millimeter wave front band |
| 2. Key parameter comparison and selection logic | ||||
| 2.1 Priority of electrical performance | ||||
| Parameter | RG-174 | RG-316 | Foamed PE line | Affect |
| Attenuation @6GHz | 1.8dBm/m | 1.7dBm/m | 0.9dBm/m | High-frequency signal integrity |
| Shielding efficiency | 70dB | 90dB | >90dB | Anti-interference ability |
| 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 | Medium | Tall | Low (easy to damage) |
| 3. Typical application scenarios and cable matching |
| 3.1 Consumer electronic products (Bluetooth/Wi-Fi) |
| Cable: RG-174 |
| Reason: 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 (such as Times LMR-200) |
| Reason: It needs to be resistant to plugging and low loss (high calibration accuracy requirements). |
| 3.3 On-board radar/5G small base station |
| Cable: PTFE insulated foam cable (such as Gore G-FLEX 150) |
| Reason: 6~24GHz low loss demand, outer diameter ≤2mm convenient for wiring. |
| 3.4 Military equipment |
| Cable: RG-316 (military standard MIL-DTL-17) |
| Reason: Resistant to extreme temperature and vibration, high shielding requirements. |
| 4. Supplementary explanation |
| 4.1 Outer diameter mismatch: MCX connectors usually support 1.0~3.0mm wire diameters, and need to be customized beyond the range (such as micro wires, special MCX heads are required). |
| 4.2 High-frequency loss: RG-174 is twice as high as foam PE wire at 6GHz, and long-distance transmission avoids use. |
| 4.3 Phase stability: For phase-sensitive applications (phased arrays), semi-rigid lines or phase-stable cables (such as Huber+Suhner S100) are preferred. |
| 4.4 Connector level: Gold-plated contact MCX (non-nickel-plated) is selected to ensure a life of >500 plugging and unplugging. |
