Micro Coaxial Cable-Micro Coaxial Cable factory-(FRS)-FRS
Test Methodology
Cable Samples:
0.8mm: Silver-plated copper inner conductor, PTFE foam dielectric, double-layer braided shield.
1.2mm: Identical materials with thicker outer conductor and dielectric.
Equipment:
Vector Network Analyzer (VNA): Keysight N5227B (10 MHz–110 GHz).
Power Meter: Boonton 4540 peak power sensor.
Phase Stability Chamber: Temperature-controlled (-55°C to +125°C).
Test Parameters:
Frequency range: 1–65 GHz.
Bend radius: 2× diameter (dynamic bending test).
Power input: 10–30 dBm.
Key Performance Metrics: 0.8mm vs 1.2mm
1. Attenuation (Loss per Meter)
Frequency (GHz) 0.8mm Attenuation (dB/m) 1.2mm Attenuation (dB/m)
10 0.85 0.62
30 1.92 1.33
60 3.15 2.04
Conclusion: The 1.2mm cable reduces loss by 25–35% due to its larger conductor cross-sectional area, minimizing skin effect.
2. Power Handling Capacity
Parameter 0.8mm Cable 1.2mm Cable
Average Power (CW) 18 W 32 W
Peak Power (1µs) 2.5 kW 4.8 kW
Thermal Rise (°C/W) 0.45 0.28
Conclusion: The 1.2mm cable supports ~78% higher power owing to better heat dissipation.
3. Phase Stability Under Bending
Test: Measured phase shift after 1,000 dynamic bends at minimum radius.
0.8mm: 4.2° cumulative phase deviation at 30 GHz.
1.2mm: 1.8° deviation under identical conditions.
Implication: The 1.2mm cable exhibits 57% better phase consistency, critical for phased-array radar and beamforming.
4. Bend Radius and Flexibility
Parameter 0.8mm Cable 1.2mm Cable
Static Bend Radius 1.6 mm 2.4 mm
Dynamic Flex Life* 50,000 cycles 25,000 cycles
Note: Cycles until 10% attenuation increase at 10 GHz.
Trade-off: The 0.8mm cable offers 2× better flexibility but sacrifices power and phase performance.
Practical Application Scenarios
When to Choose 0.8mm:
Space-constrained designs: Endoscopic tools, drone FPV systems.
High-flex requirements: Robotic arms, wearable sensors.
Cost-sensitive projects: 0.8mm cables cost 20% less than 1.2mm versions.
When to Choose 1.2mm:
High-power mmWave systems: Automotive radar (77–81 GHz), satellite uplinks.
Phase-sensitive arrays: 5G mMIMO, quantum computing interconnects.
Harsh environments: Outer conductor thickness improves crush resistance by 40%.
