Cheminax Coaxial Cables
Small, lightweight coaxial cables
Applications
Cheminax controlled electrical cables are used in the
aircraft and aerospace industries. They have a wide
range of applications in missiles, avionics, radio-
frequency and microwave systems, computers, security
and surveillance systems, and communications.
Cheminax coaxial cables were designed to solve
interconnect problems in electronic systems, such as
computers, military equipment, and other areas of
high-density packing, where cables are required to
perform to more exacting specifications than standard
radio-grade (RG) or UL recognized (UR) constructions.
Tyco Electronics’ advanced materials technology has
allowed the design and development of Raychem
Cheminax miniature coaxial cables that offer
substantial savings in size and weight while improving
mechanical performance and reducing attenuation.
Cables can be designed that are either smaller and
lighter than standard RG and UR cables or provide
significantly lower attenuation and capacitance with no
significant increase in size.
Features and benefits
Light weight, small size.
Temperature range of –65°C to 200°C.
Low capacitance and attenuation.
High velocity of propagation.
High flexibility.
