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 Rigid rectangular waveguide water load CPR 284 F 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.

One application area of the SPINNER Rigid rectangular waveguide water load CPR 284 F is in measurement environments. It is characterized by its excellent IM properties and optimized electrical and mechanical tolerances.

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 700 kW.

The load offers an interface R 32.

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.

We use liquid cooling for higher power levels. A mixture is used as the coolant which guarantees frost and corrosion protection. From 10 kW we also offer recooling units and safety devices such as Carrier safety loops or temperature monitoring.

The protection class is IP 66.
