Q: What is the center conductor material of this 0.016" semi-rigid cable?

A: The center conductor is made of silver plated copper clad steel (SCCS). This provides excellent tensile strength for pulling through tight spaces while maintaining good conductivity.

Q: Can this RF cable be used for cryogenic applications?

A: Yes. This cable is specifically rated for cryogenic environments. It maintains excellent flexibility and electrical performance at temperatures as low as -55°C.

Q: What is the maximum power handling capacity?

A: The power handling depends on frequency and ambient temperature. At 1 GHz and 20°C, it can handle up to 7.4 Watts CW. At lower frequencies (e.g., 0.5 GHz), it can handle up to 10.5 Watts. Please refer to the attenuation chart for specific frequency derating.

Q: Does this semi-rigid cable support impedance other than 50 Ohm?

A: While the standard specification is 50 Ohm (±2.0), the manufacturing process allows for customization. According to the technical data, 70 Ohm and 93 Ohm variants are also available upon request.

Q: What is the attenuation (loss) at 18 GHz?

A: At 18.00 GHz, the attenuation is 13.4 dB per meter (or approximately 409 dB per 100 feet). This low-loss characteristic makes it suitable for high-frequency signal transmission.

Q: What is the lead time for bulk orders of SR-016 cable?

A: Standard stock items usually ship within 3-5 business days. For bulk orders or custom lengths, the typical lead time is 2-4 weeks, depending on the quantity and current production schedule.

Q: Do you offer custom cable assembly services (e.g., with connectors)?

A: Yes, we provide full customization services. We can assemble the 0.016" semi-rigid cable with various connectors such as SMA, SMP, or custom pins to meet your specific antenna system requirements.

Q: Can I request a sample for testing before placing a bulk order?

A: Absolutely. We understand the importance of validation in RF applications. We offer pre-cut sample for testing. Please contact our sales team for sample availability.

Q: What is the minimum order quantity (MOQ)?

A: For standard stock cable, the MOQ is flexible (often starting from 10 to100 meters). For customized assemblies, the MOQ may vary based on the complexity of the connectorization.
