7 W load DC-7 GHz SMA male IP 68


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 7 W load DC-7 GHz SMA 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 7 W load DC-7 GHz SMA male IP 68 ensures optimum protection for your highly sensitive signal transmission between transmitter and antenna on broadcast sites.

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 7 W.

The load offers an interface SMA 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 7 W load DC-7 GHz SMA 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 term SMA stands for Sub-Miniature-A. SAM connectors are quite small, but mechanically very robust due to the screwed swivel nut.
