Coupleur directionnel 12 dB

Le Coupleur directionnel 12 dB (Part number: 1200571) de la marque C-COR est un Coupleur Directionnel Coaxial avec une bande operationelle de 1.0 GHz . Le coupleur coaxial directionnel est un dispositif passif utilisé pour répartir l'énergie entre les ports. En gros, il extrait une partie de l'énergie du circuit de transmission principal et la redirige vers un ou plusieurs ports couplés. Ce type de dispositif est principalement utilisé dans le domaine de la technologie radio et présente généralement une isolation élevée entre les ports. Le couplage a un impact direct sur la perte d'insertion. Il faut donc savoir que moins les ports sont couplés, plus la perte d'insertion est faible.

A directional coupler is an unequal power divider; a splitter is an equal power divider. Both have the abbreviation TFC (trunk/feeder coupler) in their model names because they split your network’s trunk and feederlines. A line power inserter passively combines radio frequency (RF) signals with up to 90 volts alternating current (VAC) from a line power supply. This device enables a single cable to service the power and signal requirements of active modules in a broadband telecommunications network. Directional couplers, line splitters, and line power inserters consist of a main circuit board and a housing. The housing’s environmental coating protects the module from the most severe conditions. A wire mesh gasket maintains RF integrity, while a rubber gasket prevents weather from affecting the module’s operation. A 90° rotating seizure mechanism lets you install directional couplers and splitters easily in a variety of configurations. Feed‐thru connectors can be used with cable up to 0.625‐inch in diameter. Pin connectors, which enable you to accommodate larger diameters, also give better RF performance than feed‐thru connection. All models have direct‐entry ports with heat‐shrink ridges and cable strip gauges. Line power inserter is available in two models: 9‐LPI/22A and 9‐LPI/22A‐ACM‐3. The ACM‐3 model provides heavy‐duty surge protection.
