Selection Guide

1. Specifications and Characteristics of Commonly Used Adaptable Cables

Model	Outer Diameter	Center Conductor	Attenuation at 3GHz	Features	Application 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 standard	High-temperature environments, test instruments
Micro Foam PE Cable	1.5~2.2mm	0.3~0.5mm	0.50dB/m	Low high-frequency attenuation	5G/Wi-Fi
Semi-rigid Cable	1.0~3.0mm	Solid copper	0.30dB/m	Relatively stable, excellent shielding	Test calibration, millimeter-wave front-end

2. Key Parameter Comparison and Selection Logic

2.1 Priority of Electrical Performance

Parameter	RG-174	RG-316	Foam PE Cable	Impact
Attenuation @6GHz	1.8dBm/m	1.7dBm/m	0.9dBm/m	High-frequency signal integrity
Shielding Effectiveness	70dB	90dB	>90dB	Anti-interference capability
Impedance Stability	±3Ω	±2Ω	±1Ω	Reflected signal suppression

2.2 Mechanical and Environmental Adaptability

Parameter	RG-174	RG-316	Foam PE Cable
Minimum Bending Radius	15mm	25mm	30mm
Temperature Resistance Range	-40℃~+85℃	-65℃~+200℃	-50℃~+85℃
Tensile Strength	Medium	High	Low (easily damaged)

3. Typical Application Scenarios and Cable Matching

3.1 Consumer Electronics (Bluetooth/Wi-Fi)

Cable: RG-174

Reason: Cost-sensitive; frequency ≤5GHz; loss is controllable for short lengths (<0.3m).

3.2 Test Instrument Jumpers (Vector Network Analyzers)

Cable: RG-316 or low-loss foam cable (e.g., Times LMR-200)

Reason: Requires 插拔 resistance and low loss (high calibration accuracy requirements).

3.3 Automotive Radar/5G Small Cells

Cable: PTFE-insulated foam cable (e.g., Gore G-FLEX 150)

Reason: Low loss requirement for 6~24GHz; outer diameter ≤2mm for easy routing.

3.4 Military Equipment

Cable: RG-316 (Military Standard MIL-DTL-17)

Reason: Resistant to extreme temperatures and vibrations; high shielding requirements.

4. Supplementary Notes

4.1 Outer diameter mismatch: MCX connectors typically support wire diameters of 1.0~3.0mm. Customization is required for out-of-range diameters (e.g., dedicated MCX connectors for micro cables).
4.2 High-frequency attenuation: RG-174 has 2x higher attenuation than foam PE cables at 6GHz; avoid use for long-distance transmission.
4.3 Phase stability: For phase-sensitive applications (e.g., phased arrays), prioritize semi-rigid cables or phase-stable cables (e.g., Huber+Suhner S100).
4.4 Connector grade: Use gold-plated contact MCX connectors (not nickel-plated) to ensure >500 mating cycles.
