Silicon Dioxide RF Coaxial Cable

Extreme Performance Cables with Increased Redundancy (-270ºC to 1000ºC+)

About

T-Axel's phase stable cable assemblies are the only moisture resistant SiO2 cable on the market. This adds an additional layer on redundancy in the event a hermetic seal fails, a failure that won't be known until the cable is under use - which may be too late for some applications.

​

This also allows for use of non-hermetic connectors or without connectors at all: reducing costs and increasing ease-of-use for wider applications.

Long Operating and Storage Life

Minimal changes may be observed over 4 days with the cable dielectric exposed to ~90% atmospheric moisture. These cables are designed to essentially never be replaced compared to traditional organic cables.

No MOQ

T-Axel prides itself on offering no minimum order quantity with an industry leading quick lead time. We hope to support all R&D and small-volume use efforts.

  • Connectors: Please see full list of connector configurations in the product brochure at the bottom of this page
  • Inner Conductors: OFHC Copper, Copper-Clad Steel (40%), Silver-Plated Copper*, Silver-Plated Copper Clad Steel*, Other by special order
  • Outer Conductor Material: OFHC Copper
  • Outer Jacket Material: No Outer Jacket, 304L Stainless Steel Jacket, Thin-Walled Stainless Steel Jacket**, Aluminum, Dual-Layered Copper Tube (For Cryogenic Applications), Other by special order​
​
Please reach out to us if you have questions about the optimal configuration for your application
​
*Special Order Options; MOQ Applies
**Cables with the thin-walled stainless steel jacket has the same OD as the base cable size, whereas the regular stainless steel jacket will yield a cable OD slightly larger than the base size. Ex. 0.090 cable has a base OD of 2.29mm (with no outer jacket). With the 304L Jacket, the total OD comes out to 2.60 mm but the thin-walled stainless steel jacket will retain a total OD of 2.29 mm

SiO2 vs. Fluoropolymer (PTFE) RF Cables - Page 1

Working Temperature

SiO2 RF Cables: -271° C to over 1000° C 

PTFE RF Cables: -60° C to 250° C

Power Handling

Due to SiO2's high operating temperature, for the same size wire, SiO2 RF Cables can handle 10 to 100X the power PTFE RF Cables can handle.

Radiation Resistance

PTFE performs poorly in radioactive environments and will degrade above 5 x 10 rads whereas SiO2 RF Coax Cables has the best radiation resistance among all RF Cables. SiO2 RF Cables can operate above 10    rads
