RG402 is a widely used 50-ohm RF coaxial cable designed for high-frequency signal transmission. Also known as 0.141-inch coaxial cable, RG402 is available in semi-rigid, semi-flexible, and flexible constructions depending on the application. Its compact diameter, stable impedance, excellent shielding performance, and relatively low signal loss make it a popular choice for RF and microwave systems.

RG402 coaxial cable is commonly used in RF communication equipment, microwave systems, antennas, radar, satellite communication, test and measurement equipment, wireless infrastructure, and other high-frequency electronic systems.

What Is RG402 Coaxial Cable?

RG402 is a 50-ohm RF coaxial cable generally associated with a 0.141-inch (approximately 3.58 mm) diameter construction. It is commonly used where engineers need a compact transmission line with controlled impedance and good shielding.

Depending on the design, RG402 can be manufactured as a semi-rigid cable, semi-flexible cable, or flexible/hand-formable cable. Different manufacturers may use different conductor plating, dielectric materials, shielding structures, and jacket materials.

For example, HUBER+SUHNER's RG402-compatible SUCOFORM products use a PTFE dielectric and tin-soaked copper braid, with selected versions rated to 33 GHz and 165°C.

Conclusion

RG402 remains an important 50-ohm RF coaxial cable solution for high-frequency and microwave applications. Its compact 0.141-inch construction, controlled impedance, strong shielding, and flexible configuration options make it suitable for a broad range of communication, aerospace, radar, antenna, testing, and industrial electronic applications.

Leading international companies such as HUBER+SUHNER, TE Connectivity, Rosenberger, Amphenol RF, Times Microwave Systems, Pasternack, and others provide high-performance RF connectivity and cable solutions.
