1 COAXIAL . CABLES . aerospace industry Video systems Telecommunications Radio/television measuring equipment Various types of Medical devices computer systems Military equipment and weapon systems RoHS COMPLIANT. In order to meet the 2002/95/CEE European Di- rective, AXON' Cable has replaced their high strength silver plated copper alloy conductors (SPTF) with a silver plated copper alloy conduc- tor (SCA) with equivalent performance but heavy metal free. The AXON' SCA conductors do not contain cadium. They are RoHS compliant. SPECIAL VERSIONS. PICO-COAX . FLEXIBLE MINIATURE COAXIAL CABLES . - Flexible miniature COAXIAL CABLES offering a good com- promise between a small diameter ( < mm) and a capacitance of 50 to 100 pF/m. - Laying up of more than 500 PICO-COAX into MULTI- PICO-COAX CABLES . - Manufacture of harnesses : MULTIPICO-COAX CABLES can be terminated by different types of connectors.

FLEXIBLE LOW LOSS MICRO ASSEMBLIES. - The use of CELLOFLON dielectrics makes it possible to manufacture very low loss microwave assemblies ( AXOWAVE 8N : mm, dB at 18 GHz). which can be used at high frequencies (up to 50 GHz). - These assemblies are terminated with SMA, N, TNC. type or metric connectors depending on the type of Cable . AXOWAVE datasheets show the detailed characteristics of the whole standard product range. Any special request can be studied. TECHNICAL GLOSSARY. COAXIAL CABLES . The use of COAXIAL CABLES extends to every application in CHARACTERISTIC IMPEDANCE which a signal must have a minimum distortion and Term representing the relationship between the voltage and attenuation or where elimination of external interference current in a Cable of supposedly infinite length.

3 There are plays a leading part. three main classes of characteristic impedance for COAXIAL CABLES : 50 , 75 and 95 . The use of a COAXIAL Cable helps to prevent many of the problems The formula defining characteristic impedance may be written created by bifilary wires : the twin conductor construction of coaxials as follows : (central conductor and shield) separated by a dielectric prevents the D reception of outside interference, and at the same time, the loss of zc= Log10 in .. d the electromagnetic wave. Different types of coaxials are determined by the materials employed CAPACITANCE (conductors and dielectrics), the outer diameter, the characteristic Property of a COAXIAL Cable to store electric charge when a impedance, the capacitance, the attenuation and the frequency difference in potential energy exists between the two conduc- range. tors. This will depend on the geometry of the Cable and on the The most widely used COAXIAL CABLES are those according to the Ame- nature of the insulation and may be defined as follows : rican norm MIL-DTL-17, the RG (Radio Frequency Government) refe- 24,12.

Attenuation is the sum of losses in the conductor and in the For small, flexible, high performance COAXIAL dielectric which determines the exponential loss occuring to a CABLES AXON' has taken out a patent on signal during a transmission in a Cable .
