Acoplador direcional de 12 dB

O Acoplador direcional de 12 dB (Part number: 1200571) da marca C-COR é um Acoplador Direccional Coaxial com uma banda operando de 1.0 GHz . O acoplador coaxial direccional é um dispositivo passivo utilizado para dividir a energia entre portas, extrai uma porção de energia do circuito de transmissão principal e redirecciona-a para um ou mais portas acopladas. Este tipo de dispositivo é utilizado principalmente no campo da tecnologia de rádio e tem normalmente um isolamento elevado entre as portas. O acoplamento tem um impacto directo sobre a perda de inserção, daí quanto menos acopladas as portas, menor é a perda de inserção.

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.
