Nonmagnetic cables are key to transmit RF signals within a magnetic field

Non-Magnetic RF Interconnect Solutions

Non-magnetic coaxial cables and connectors are primarily used in applications that must transmit RF signals within a magnetic field, such MRI diagnostic imaging systems, and quantum computers. For example, quantum computers use non-magnetic components in key areas of the signal path to eliminate potential interference with applied magnetic fields. MRI systems require non-magnetic RF interconnects to send and receive pulsed RF signals; the presence of any magnetic material in these components may interfere with the magnetic field and reduce the accuracy of images.

LMR Coaxial Cable Family
Non-magnetic coaxial cables and connectors are primarily used in applications that must transmit RF signals within a magnetic field

A non-magnetic, or non-metal coaxial cable or connector must be “invisible” to the magnetic field, which requires very low susceptibility and no field distortion. Non-magnetic RF connectors are mainly used in applications where a high signal-to-noise ratio (SNR) is required. Nonmagnetic connectors are available in various interface sizes, the most popular ones are MCX and SMP.

At Times Microwave Systems, we build hermetically sealed custom coaxial cabling assemblies that address the need for reliable performance in grueling environments by utilizing advanced manufacturing techniques that ensure zero electric field distortion.

TCOM® is a UV-resistant polyethylene jacketed cable designed for 20-year service outdoor use. The bending and handling characteristics are significantly better than any air-dielectric and corrugated hardline cables.


The SPX family of low-PIM coaxial cables are a flexible and durable option well-suited for outdoor use. SPX line is available in any required connector configuration and length.


TFT-5G assemblies are ultra-flexible, plenum & outdoor, PIM-rated coaxial cable assemblies. Capable of performance up to 6 GHz, these cables are well suited for many 5G applications such as wireless networks, satellite communications, and machine-to-machine controls.


TCA is a lightweight, low-loss, high-temperature, high-flexibility cable for navigation, collision, avoidance, and communication systems. It is ideal for applications facing critical electrical and mechanical requirements. TCA provides excellent flexibility for seamless routing through tight runs.


The QEAM (Quick Erecting Antenna Mast) assemblies are perfect for demanding, mission-critical applications, where reeling and unreeling are required over a wide temperature range. Its performance has been proven on systems such as the Hawk and Patriot Missile, among other mission-critical defense applications.


Our TRAD™ and NuTrac™ radiating cables provide RF coverage in difficult-to-cover structures. Examples include rail and transit tunnels, underground mines, subways, metal-hulled ships, offshore oil rigs, nuclear power plants and buildings with metal supporting structures. Radiating cables can carry multiple frequencies on a single cable, and function as a single broadband antenna. The radio frequency signals are fed between the transmitter and antenna while a controlled amount of energy is leaked into the surrounding environment providing the necessary RF coverage.
