RG-400 is a high-performance, flexible coaxial cable commonly used in RF and microwave applications, particularly where high-frequency signal transmission and minimal signal loss are critical.
- Impedance: 50 Ohms
- Capacitance: Approximately 29.4 pF/ft (96.5 pF/m)
- Velocity Factor: 0.695
- Frequency Range: Effective up to 3 GHz
- Attenuation: Varies with frequency; for example, around 9.6 dB per 100 feet at 400 MHz
Construction Details:
- Inner Conductor: Silver-coated copper wire with a diameter of 0.98 mm (19 strands of 0.203 mm each)
- Dielectric Insulation: Solid Polytetrafluoroethylene (PTFE) with a diameter of 2.95 mm
- Shielding: Double silver-plated copper braided shield; inner braid coverage of 97% and outer braid coverage of 94%
- Outer Jacket: Fluorinated Ethylene Propylene (FEP) with a diameter of 4.95 mm
Mechanical and Environmental Properties:
- Minimum Bending Radius: 25.4 mm (1 inch)
- Operating Temperature Range: -55°C to +200°C
- Weight: Approximately 0.089 kg per meter
These characteristics make RG-400 suitable for applications such as internal wiring of electronic equipment, RF signal transmission, and situations requiring high flexibility and durability under varying environmental conditions.
For specific configurations, such as the RG-400 N-Male to BNC-Male Coax Cable, Northcomm Technologies offers precision-manufactured assemblies designed for high-reliability and mission-critical environments. These assemblies feature fully assembled Thermax RG-400B/U coaxial cables with connectors from reputable manufacturers like Amphenol RF, Times Microwave, or RF Industries. Each assembly includes vinyl protective connector covers, low-smoke zero halogenating heat shrink product ID labels, and RF sweep data ranging from 100 KHz to 2.7 GHz. All assemblies are designed and produced in the United States.
