2. Description of key features

2.1. High-frequency performance advantages

PTFE insulation: higher temperature stability than PE material, phase drift < 0.5°/m @3GHz silver-plated inner conductor: reduce skin effect loss (15% lower than pure copper@3GHz)

Loss comparison (@3 GHz): RG174 : 29.8 dB/30m

RG316: 23.5 dB/30m (↓21%) 2.2 Double shielding structure

Temperature range	-40℃ ~ +85℃	-65℃ ~ +200℃	-50℃ ~ +85℃
tensile strength	medium	Tall	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 unplugging, low loss (high calibration accuracy requirements).

3.3 Vehicle radar/5G small cell station

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

Reason: 6~24GHz low loss requirements, outer diameter ≤2mm for easy wiring.

3.4 Military equipment

Cable: RG-316 (Mi-Label MIL-DTL-17)

Reason: Resistant to extreme temperatures, vibration, and high shielding requirements.

4. Supplementary instructions

4.1 Outer diameter mismatch: MCX connectors usually support 1.0~3.0mm wire diameter, which needs to be customized beyond the range (such as micro wires require a dedicated MCX head).

4.2 High frequency loss: RG-174 has 2 times higher loss than foamed PE wire at 6GHz, and is avoided for long-distance transmission.

4.3 Phase stability: For phase-sensitive applications (phased arrays), prefer semi-rigid wires or phase-stabilized cables (such as Huber+Suhner S100).

4.4 Connector Grade: Gold-plated contacts MCX (non-nickel plated) are selected to ensure a > 500 plugging and unmating life.
