What are RG402 Coaxial Cables?

RG402 Coaxial Cables are a type of cable that has been designed to offer an excellent signal integrity and low signal attenuation, making them suitable for a wide range of wireless and microwave applications.

RG402/U

RG402/U Cable Construction

The RG402/U is a 50-ohm coaxial cable with an overall diameter of 0.141 inches and a voltage rating of up to 2500 Vrms. It has an internal silver-coated copper-clad steel (SCCS) conductor (carrying the electrical signal), which is enclosed by an insulation layer made of Polytetrafluoroethylene (PTFE). The insulation layer is then completely enclosed by a bare copper tube (BC Tube) shield that forms the outer conductor and also provides shielding against electromagnetic interference (EMI). 

The RG402/U cable exhibits capacitance of approximately 29.4 pF/ft (96.5 pF/m), signal attenuation of around 7.2 dB/100 ft at 400 MHz (signal attenuation of the cable depending on the frequency), and has a velocity of propagation of 69.5%.It has a center conductor measuring 0.036 inches (0.9144 mm) in diameter and an insulation layer measuring 0.119 inches (3.02 mm) in diameter. This cable is ideal for use in radio frequency communications in the gigahertz range, microwave circuits, and radar. It has an operating temperature of -55˚C to + 100˚C.
