SPINNER loads offer outstanding electrical and mechanical properties
The modular SPINNER system for loads offers you great flexibility in the selection of your components. It allows you to configure power, frequency range and connectors according to your individual requirements. The advantages are obvious: cost savings through standardization and reliable technical quality.
The 50 W load DC-4 GHz N male is placed to the end of the signal path and thus guarantees the correct impedance termination. This reduces disturbing reflections and ensures the maximum performance and quality of the overall system. You can individually combine your attenuator and adapt it to the requirements of your local installation.
When used for in-building installation, a 50 W load DC-4 GHz N male allows you to ensure continuous power and power radiation of your antennas within your building.
Outstanding RF characteristics, best possible passive intermodulation and VSWR
The load enables you to transmit high-frequency signals reliably and flawlessly with optimum protection of your sensitive equipment in a power range up to 50 W.
The load offers an interface N male.
SPINNER loads can be mounted vertically or horizontally. Only in a few cases a certain orientation is required for a product and therefore explicitly stated in our product data sheets.
The 50 W load DC-4 GHz N male is cooled passively by convection i.e. the heat dissipation via the cooling fins. Due to the flexible mounting options, optimum air circulation and thus cooling can be achieved.
The protection class is IP 50.
The N-coaxial connectors were named after their inventor Paul Neill, who developed this standard for RF connectors in 1942. Often, however, the name also relates to the Navy Connector. Type N connectors can be used at frequencies up to 11 GHz, high-precision types up to 18 GHz. It is typically used in mobile communication applications with demanding mechanical and electrical requirements. SPINNER exclusively manufactures connectors with non-slotted outer conductor contacts and a special sealing profile in the connector head instead of the flat seal disk, specified by IEC or CECC. This ensures the most reliable sealing function.
