RG188A/U Low-Outgassing High-Temp Miniature Coax 50 Ohm for satellite system
RG188 A/U 50Ω Miniature High-Temperature Coaxial Cable

M17/138-00001 | 50Ω | 3 GHz | 250°C | Low Outgassing | 16.2 g/m

Built for the Environments Where Ordinary Coax Fails

RG188 A/U is no ordinary miniature coax. Featuring a stranded silver-plated copper-clad soft steel conductor, extruded PTFE dielectric, silver-plated copper braid and white PTFE jacket, it maintains reliable performance from -55°C to +250°C. This cable is purpose-built for three high-value application scenarios, environments where conventional cables cannot endure:

  • Satellite and spacecraft vacuum environments – where low outgassing is mandatory.

  • Aerospace and engine-bay high-temperature sensors – where 250°C and vibration resistance are required.

  • Mil itary UHF and portable radio systems – where 50Ω precision, 3 GHz bandwidth, and MIL-DTL-17 reliability matter.

  • RoHS Compliant – Environmentally responsible materials.

Frequently Asked Questions

Q: Why is the white PTFE jacket important?
A: White taped PTFE contains no carbon black, resulting in low outgassing and UV resistance. It is ideal for vacuum, space, and high-cleanliness environments where contamination is unacceptable.

Q: Can RG188 A/U be used in vacuum?
A: Yes. The white PTFE jacket is low outgassing and suitable for vacuum chambers, satellites, and spacecraft.

Q: Can RG188 A/U be used in a 75Ω system?
A: No. It is a 50Ω cable. Using it in a 75Ω system will cause impedance mismatch and high VSWR. For 75Ω systems, consider our RG187 A/U.

Q: What is the maximum frequency?
A: The RG188 A/U is specified up to 3 GHz, covering UHF, WiFi 2.4G, GPS, Bluetooth, SDR, and low S-band applications.

Q: What is the minimum bend radius?
A: The static minimum bend radius is 12.7 mm. Avoid repeated flexing beyond this radius.

Q: What connectors are available?
A: We offer 50Ω connectors including SMA, BNC, TNC, SMB, MCX, and custom assemblies.
