Description
The CRG141 low-loss semi-rigid coaxial cable is designed for high-frequency RF and microwave applications requiring superior shielding, mechanical precision, and thermal durability. Operating up to 26.5 GHz with a 50 Ω impedance, it provides consistent electrical performance and structural stability for aerospace, defense, and metrology systems. Explore the CRG Series – Low-Loss Semi-Rigid Coaxial Cables for additional models.
The CRG141 cable features a 0.99 mm silver-plated copper core, PTFE dielectric, and a 3.58 mm seamless annealed copper outer conductor plated with a ternary alloy for corrosion protection. This design achieves >165 dB shielding effectiveness, ensuring minimal signal leakage and maximum phase stability even under vibration or bending.
Attenuation remains as low as 0.32 dB/m @ 1 GHz and 1.88 dB/m @ 26.5 GHz, supporting high-power transmission up to 0.55 kW @ 1 GHz. The cable’s velocity of propagation is 76%, and its minimum bend radius is 10 mm, allowing precise routing in compact assemblies without compromising impedance stability.
Built for environments ranging from –55 °C to +250 °C, the CRG141 provides consistent attenuation and shielding across extreme temperature cycles. Its solid copper construction ensures long-term reliability for systems requiring repeatable electrical and mechanical accuracy.
