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 Coaxial precision load 50 W 0.25-3.8 GHz 4.3-10 female low PIM without handle and pads 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 Coaxial precision load 50 W 0.25-3.8 GHz 4.3-10 female low PIM without handle and pads 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 50 W.

A SPINNER Coaxial precision load 50 W 0.25-3.8 GHz 4.3-10 female low PIM without handle and pads guarantees outstanding IM characteristics with maximum passive intermodulation (IM3) of -165 dBc and low VSWR values over the entire frequency range and during the entire operating time.

The load offers an interface 4.3-10 female.

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 Coaxial precision load 50 W 0.25-3.8 GHz 4.3-10 female low PIM without handle and pads 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 4.3-10 connector system was designed to meet the latest requirements in mobile communication in terms of size, robustness, performance, and other parameters. Its small footprint supports the use of smaller components, mitigates risks if equipment is assembled without due care, and delivers outstanding electrical performance.
