0.024'' Semi-Rigid Coax Cable 50 Ohm Low Loss Antenna Test Cable with PTFE Dielectric

The SR-024 0.024 inch (0.584mm) semi-rigid coax cable is precision engineered for microwave engineers who demand absolute signal integrity in confined spaces. The seamless copper tube outer conductor provides 100% RF shielding with effectiveness exceeding 110 dB, eliminating the signal leakage common in braided constructions. A silver-plated copper-clad steel center conductor and PTFE dielectric maintain 50 Ohm impedance with 70% velocity of propagation across the full DC to 40 GHz range. Designers choose SR-024 microwave cable when building custom test probes, connecting VNA ports to devices under test, or creating permanent PCB interconnects where mechanical stability matters. Available with custom cut lengths, SMA pigtail options, and formed shapes to your specifications, backed by a 10 meter minimum order quantity that supports both prototyping and production.

Q: What is the maximum frequency for this 0.024 inch semi-rigid cable?
A: DC to 40 GHz with usable performance through Ka band. Insertion loss at 40 GHz is 15.2 dB per meter, which works well for short cable runs under 12 inches in most test applications.

Q: Can I solder SR-024 directly to a PCB?
A: Yes. The silver-plated copper-clad steel center conductor solders reliably with standard techniques. Keep soldering temperature between 260-290°C with dwell time under 3 seconds to protect the PTFE dielectric from damage.

Q: What is the minimum bend radius for forming?
A: 0.050 inches (1.3 mm) for static installation. The cable can be formed using radiused tools. Avoid repeated bending at the same point as this work-hardens the copper tube and may cause cracking.

Q: What is the minimum order quantity for SR-024?
A: 10 meters minimum, with custom cut lengths available down to 1 inch increments. This low MOQ makes the cable accessible for prototyping and R&D projects where full spools aren't practical.

Q: What connector options do you offer?
A: Standard options include bare cable ends, SMA female and male pigtail assemblies, and fully connectorized cables. Other interfaces like 2.92mm are available on request. All connectorized assemblies are 100% continuity tested.

Q: Can you provide pre-formed shapes to my mechanical drawing?
A: Yes, we are a semi rigid coax cable manufacturer who accepts OEM & ODM. Send a mechanical drawing, 3D model, or dimensioned sketch, and we will deliver cables formed to net shape with ±0.5mm tolerance. Forming can be done before or after connector installation based on your requirements.

Q: What is the velocity of propagation and why does it matter?
A: 70% VP means the electrical length is approximately 1.43 times the physical length. This is critical for phase-sensitive applications like antenna arrays or time-domain measurements where electrical delay must be precisely matched across multiple channels.

Q: Is SR-024 semi-rigid cable RoHS compliant?
A: Yes, fully RoHS compliant and manufactured with materials suitable for defense, aerospace, and commercial applications.

Q: What is the shielding effectiveness for SR-024?
A: The solid copper tube provides complete 100% shielding with no signal leakage paths. Unlike braided cables that typically offer 80-95% coverage, this construction ensures no interference enters or exits the transmission line.

Q: Can I order a small quantity for evaluation before production?
A: With our 10 meter MOQ, you can order as little as the MOQ goes to test compatibility with your designs before scaling up.
