RF electrical cable Conformable®

coaxialRF-shieldedsemi-rigid

Short description
Conformable or hand-formable (Braided Jacket) cables feature a tin-filled braid with a metal foil underlay and are offered in the same diameters as semi-rigid types. High-frequency RF cable assemblies are available in flexible and semi-rigid variants with space/orbit qualifications, suitable for satellite payloads (GEO/MEO/LEO), deep space probes, ground antenna networks and space robotics.

Features & Benefits

• Frequency range: DC to 18 GHz
• Hand-formable with high isolation
• Polyolefin jacket option (BJ085W)
• Compatible with standard RF connectors
• Phase-matched sets available (±1° per GHz standard)
• Custom solutions to customer specifications (marking, part numbers)
• Subjected to extensive space qualifications

Overview
Conformable® (hand-formable, BJ — Braided Jacket) cables combine a tin-filled braid with a metal foil underlay and share diameters with semi-rigid types. BJ141 is the most commonly used size in the hand-formable family, offering a cost-efficient assembly with high RF performance. Relative to .141 semi-rigid, BJ141 presents slightly higher loss and reduced shielding but eliminates the need for detailed bending drawings.

BJ085 serves as a cost-saving alternative to .086 semi-rigid, removing the need for expensive bending documentation. BJ085 can be delivered under manufacturer or customer part numbers and the BJ085W variant adds a polyolefin outer jacket for added protection.
