Frequency Range: 2–40 GHz (X-band to Ka-band).
Key Requirements:
Phase Stability: <0.3° variation over -55°C to +125°C. Shielding Effectiveness: >120 dB to suppress sidelobe interference.
Example: The AN/SPY-6(V)1 radar by Raytheon uses 3.0mm semi-rigid cables with aluminum jackets, achieving a 30% improvement in signal-to-noise ratio over flexible alternatives.
B. Automotive Radar (77 GHz)
Autonomous vehicles rely on semi-rigid cables for millimeter-wave radar modules in ADAS (Advanced Driver Assistance Systems).
Insertion Loss: <0.25 dB/cm at 77 GHz (e.g., Rosenberger’s 1.19mm cable).
Material: Silver-plated copper outer conductor to minimize surface roughness losses.
Key Features:
Thermal Cycling: Withstands 1,000+ cycles (-65°C to +150°C).
Outgassing Compliance: NASA-approved PTFE dielectrics (TML <1%).
Case Study: SpaceX’s Starlink satellites employ 2.2mm semi-rigid cables with gold-plated connectors, reducing passive intermodulation (PIM) to <-160 dBc.
B. Ground Station High-Power Feeds
High-power uplink systems demand cables capable of handling kW-level RF power without arcing.
Power Handling: Up to 500 W average power (3.5mm cables with air-enhanced PTFE dielectric).
VSWR: <1.15:1 at 18 GHz (per MIL-STD-348).
Frequency Bands: 24–47 GHz (n258/n260/n261).
Phase Matching: ±1.5° across 64-element arrays (e.g., Ericsson’s Streetmacro 6701).
B. mmWave Small Cells
For E-band (70/80 GHz) backhaul links, semi-rigid cables minimize loss in compact RF front-end modules.
Insertion Loss: <0.1 dB/mm at 80 GHz (Rogers UltraLaminate 3000 dielectric).
Bend Radius: Pre-shaped during manufacturing to fit tight enclosures.
Repeatability: <0.01 dB insertion loss variation after 10,000 mating cycles.
Example: Keysight’s N4421B calibration kits use 1.85mm semi-rigid cables with phase-stable performance.
B. Spectrum Analyzer Probes
In EMI/EMC testing, semi-rigid cables prevent ambient noise pickup.
Shielding Effectiveness: >130 dB at 10 GHz (double-layer copper-tin shields).
Non-Magnetic Materials: CuNi9Sn2 outer conductors (magnetic susceptibility <0.01 ppm).
Loss Tangent: <0.0003 at 300 MHz (PTFE dielectric).
Peak Power Handling: 10 kW (1 µs pulse width) for 5.0mm cables.
EMI Shielding: >90 dB from 2–18 GHz (MIL-DTL-87104).
B. Avionics Data Links
Flight control and in-flight entertainment systems use semi-rigid cables for interference-free operation.
Fire Safety: Fluoropolymer jackets compliant with FAA AC 20-135.
