HCJ630 Flexible Low-Loss Microwave Coax for Medical Imaging and Diagnostic Equipment

50Ω | 6.30 mm OD | 81% Velocity | VSWR ≤ 1.25 | 0.24 dB/m @ 1 GHz

The HCJ630 is a premium flexible low-loss microwave coaxial cable engineered for modern communication and test systems where every fraction of a dB matters. By utilizing an Expanded PTFE dielectric, it achieves an outstanding 81% velocity of propagation and remarkably low insertion loss—just 0.24 dB/m at 1 GHz and 0.38 dB/m at 2.45 GHz. Unlike rigid or semi-rigid microwave cables, the HCJ630 is built for movement. Its 19-strand silver-plated copper inner conductor and rugged Polyurethane (PUR) jacket deliver exceptional flexibility and mechanical durability, making it the perfect choice for test bench jumpers, 5G antenna feeders, and high-density microwave interconnects. The combination of a copper foil + tinned copper braid shield ensures a highly stable impedance and an excellent VSWR of ≤ 1.25.

• Expanded PTFE Dielectric – Achieves an 81% velocity of propagation and ultra-low attenuation.

• Ultra-Low Insertion Loss – 0.15 dB/m at 400 MHz, 0.24 dB/m at 1 GHz, 0.38 dB/m at 2.45 GHz.

• Outstanding VSWR ≤ 1.25 – Excellent impedance matching for critical microwave systems.

• Extreme Flexibility – 19-strand inner conductor and PUR jacket allow tight bending and frequent movement.

• PUR Jacket – Highly abrasion-resistant, oil-resistant, and chemically stable.

• Dual-Layer Shield – Copper foil + tinned copper braid provide 100% coverage and excellent EMI protection.

• 6.30 mm Compact OD – Easy to route in dense equipment racks and antenna arrays.

• 50 ± 2.5Ω Impedance – Precision engineered for RF and microwave systems.

The HCJ630 stands out as a true high-performance microwave solution by combining low loss with real-world flexibility. While traditional low-loss microwave cables are often rigid and difficult to route, the HCJ630’s expanded PTFE dielectric and PUR jacket deliver industry-leading signal efficiency without sacrificing handling. This makes it ideal for applications where cables are constantly moved or bent, such as lab test benches. Its dual-layer shield design ensures that the impedance stays stable and VSWR remains exceptionally low (≤ 1.25), keeping your signals clean. Whether you are building 5G infrastructure, assembling microwave test kits, or routing signals in dense communication racks, the HCJ630 delivers the performance and durability you need.

• 5G Base Station Antenna Feeders – Low loss at 2.45 GHz and 3.5 GHz preserves transmitter power.

• Microwave Test Jumper Cables – PUR jacket and stranded conductor handle daily flexing and movement.

• RF Test Benches – VSWR ≤ 1.25 ensures accurate measurement results.

• Indoor Distributed Antenna Systems (DAS) – Flexible routing in tight spaces.

• Microwave Communication Links – Low attenuation up to 6 GHz for point-to-point links.

• High-Density Rack Interconnects – Compact 6.30 mm diameter simplifies cable management.
