CTR Series: On-Board High Temperature & Phase Stable Coaxial Cable
Struggling with signal failure under extreme heat or phase drift during on-board maneuvers? AO Microwave's CTR Series provides high-temperature, phase-stable coaxial cables up to 40 GHz. Featuring stranded silver-plated copper cores and PI+PTFE jackets, they resist up to 400°C for 400s. With 90 dB shielding and outer diameters from 3.60mm (CTR360) to 5.40mm (CTR500), they ensure stable, low-loss RF paths for missile-borne comms and extreme-temperature chambers.
On-Board High Temperature & Phase Stable Coaxial Cables
Are you facing critical signal distortions during extreme thermal transients on missile-borne systems, or looking for high-performance cabling that can withstand thermal testing environments without phase drift? AO Microwave’s high-precision CTR Series on-board coaxial cables are engineered to resolve these harsh conditions, ensuring your high-frequency RF systems operate with high reliability.
By combining specialized, high-temperature composite materials with advanced electrical shielding, the CTR Series brings direct, tangible benefits to your advanced defense and aerospace platforms:
- Survive Severe Thermal Transients (Up to 400°C): Designed with a specialized PI+PTFE (Polyimide + Polytetrafluoroethylene) composite jacket. It is rated to withstand extreme temperatures up to 400°C for 400 seconds, preventing cable melt-down during high-speed atmospheric flight or thermal testing.
- Highly Stable Phase Tracking under Temperature Cycling: Utilizes high-grade solid PTFE dielectrics and stranded silver-plated copper inner conductors. This structure keeps electrical length variations extremely low under thermal shocks, securing precise phase and amplitude tracking.
- Easy Routing in Narrow & Complex Cabinets: Features flexible stranded inner conductors, allowing the cable to bend easily in tight spaces (static bend radius down to 18 mm for CTR360) and reducing mechanical strain on delicate internal connector solder joints.
- Exceptional Electro-Magnetic Containment (>90 dB): Equipped with a high-density, double-shielded silver-plated copper structure. This provides excellent shielding effectiveness to block out-of-band noise, maintaining clean signal paths on active on-board environments.
Review our detailed physical and electrical specification tables below to select the exact CTR Series jacket size—ranging from the 40 GHz CTR360 (3.60 mm OD) to the high-voltage CTR500 (5.40 mm OD)—designed to protect your extreme-temperature links from operational failures.
CTR Series Coaxial Cable Selection & Engineering Guidelines
When integrating high-frequency coaxial lines into dynamic aerospace pedestals or extreme temperature testing environments, managing space constraints and heat-handling boundaries is essential:
Selecting Sizing According to Frequency
The outer diameter (Jacket OD) of the CTR Series directly corresponds to its model number (ranging from 3.60 mm for CTR360 to 5.40 mm for CTR500). For ultra-compact system routing up to 40 GHz, the thin profile of CTR360 is ideal. If your setup requires higher voltage withstand capability (up to 1500V DC), our larger CTR500 provides excellent dielectric insulation.
Withstanding Extreme Thermal Transients
Cables deployed in missile-borne telemetry or testing chambers must endure severe, short-duration heat spikes. Our specialized PI+PTFE composite jackets are rated for 400°C for 400 seconds. This protection prevents the insulation from failing during rapid thermal cycles, securing your mission data.
Overcoming Critical Environmental & Physical Challenges
On-board platforms and testing chambers operate under brutal conditions. We optimize our CTR Series to eliminate common system bottlenecks:
Preventing Solder Joint Stress and Connector Shear
Standard high-temperature cables are physically stiff, transferring bending stress directly to the connector's internal solder joints. During repeated movement or routing, this stress can shear the joint, causing physical failures. Our CTR Series resolves this by using an ultra-soft stranded silver-plated copper inner conductor. This multi-strand core absorbs mechanical flexing forces, preventing tension from pulling at your connector joints.
Maintaining High Shielding Effectiveness
In high-density system cabins, closely routed coaxial lines are highly susceptible to electromagnetic cross-talk. To block signal leakage, our CTR Series incorporates a high-density, double-shielded silver-plated copper structure. This configuration provides over 95% optical coverage, achieving an exceptional shielding effectiveness of > 90 dB to prevent cross-talk.
