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 25 W load DC-4 GHz 7-16 male IP 68 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.
The SPINNER 25 W load DC-4 GHz 7-16 male IP 68 is very often used as standard product for the installation and calibration of macro mobile radio stations (BTS).
When used for in-building installation, a 25 W load DC-4 GHz 7-16 male IP 68 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 25 W.
The load offers an interface 7-16 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 25 W load DC-4 GHz 7-16 male IP 68 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 68.
The 7-16 connector has become the most widely used coaxial connection system for mobile communication systems, due to its excellent mechanical and electrical properties. In order to achieve the industry leading intermodulation performance SPINNER applies silver-plating on all inner and outer conductor parts of the standard connector. As a supporting measure, we use exclusively non-magnetic materials, and we have minimized the number of RF contact points. The connection is especially suited for transmitting medium or high power indoors and outdoors.
