R 900 to 1.00 mm female precision adapter 75-110 GHz ruggedized


SPINNER adapters offer outstanding electrical and mechanical properties

Adapters are used to connect transmission lines with of different interface sizes (so-called inter-type or between-lines adapter) or within one size but different interface genders (so-called within-type or in-line adapter).

SPINNER high frequency adapters are optimized for quality and performance and are designed for the lowest possible reflection factors. The outstanding electrical and mechanical properties, the simple installation and the high reliability make SPINNER high-frequency adapters one of the most efficient and cost-effective transition connectors on the market. Precision adaptors with RF quality grade 0 are available upon request.

The SPINNER R 900 to 1.00 mm female precision adapter 75-110 GHz ruggedized is characterized by its excellent low IM values and its longevity for test and measurement laboratories. A SPINNER precision adapter increases the lifetime of the connector of the analyzer considerably and thus saves money in the long term.

R 900 to 1.00 mm female precision adapter 75-110 GHz ruggedized enables you to reliably transmit radio-frequency signals in the frequency range from 75 to 110 GHz.

The adaptor offers a transition from interface R 900 to interface 1.0 mm female. The connector has a straight direction.
