RF Coaxial Cable - Flexible vs Solid

Rayfast are pleased to be able to supply RF Coaxial Cable.

The key types of Coax are flexible (multistrand) or a solid centre conductor. The benefits of each can be determined by the application
where they are being used.

Some factors that come into play to help determine the best solution:

• Impedance (50 Ohm, 75 Ohm and 120 Ohm)

• Operating frequency (Dc – 85 Ghz)

• Signal Loss (Attenuation at a specific frequency)

• Screening effectiveness (Single or multi braid screens)

• Bend radius (based on the O/D)

• Connector termination (Frequency ratings and suitability for the cable)

Flexible vs Solid RF Coaxial Cable

Flexible

Solid

Easy to handle

Ideal for Dynamic applications

Suited to > 48 GHZ

Sustain vibration

Low attenuation

Moveable connections

Lower cost

Lower tooling cost

Weight

Screening effectiveness

If we focus on these initial ones Rayfast hold stock of we can help engineers and procurement find the optimal product
and look at alternatives to existing products.

If the cable does not need to move and can be fixed in place then solid is the best option to give the
lowest signal loss and screening effectiveness.

We also offer an RF cable selection guide to help navigate the best solution giving the technical information
required to match the cable to the system.

Our Guide to RF cable will help with defining the best cable for your application with all the specifications in the table in a handy way to give you the key specification criteria. Our technical team at Rayfast are on hand to help and can work through your requirements to help with defining alternative cables to meet the required specification.
