| Selection guide | |||||
| 1. Specifications and characteristics of commonly adapted cables | |||||
| Model | Outside diameter | Central conductor | 3GHz loss | peculiarity | Applicable scenarios |
| RG-174 | 2.8mm | 7*0.16mm | 0.82dB/m | Flexible, easy to install, and 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 foamed PE wire | 1.5~2.2mm | 0.3~0.5mm | 0.50dB/m | High frequency loss is low | 5G/Wi-Fi |
| Semi-steel wire | 1.0~3.0mm | Solid copper | 0.30dB/m | Relatively stable and good shielding | Test calibration, mmWave front |
| 2. Comparison of key parameters and selection logic | ||||
| 2.1 Electrical performance priority | ||||
| parameter | RG-174 | RG-316 | Foamed PE wire | effect |
| 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 | Reflected signal suppression |
| 2.2 Mechanical and environmental adaptability | |||
| parameter | RG-174 | RG-316 | Foamed PE wire |
| Minimum bend radius | 15mm | 25mm | 30mm |
| Temperature range | -40℃~+85℃ | -65℃~+200℃ | -50℃~+85℃ |
| tensile strength | medium | high | Low (easily damaged) |
| 3. Typical application scenarios are matched with cables |
| 3.1 Consumer Electronics (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 (e.g. 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. |
