NEX10® female to 3.5 mm male DC-20 GHz precision adapter


SPINNER adapters offer outstanding electrical and mechanical properties

Adapters are used to connect transmission lines with 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 NEX10® female to 3.5 mm male DC-20 GHz precision adapter 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.

Outstanding RF characteristics, best possible passive intermodulation and VSWR

A NEX10® female to 3.5 mm male DC-20 GHz precision adapter enables you to reliably transmit radio-frequency signals in the frequency range from DC to 20 GHz.

The adaptor offers a transition from interface NEX10® female to interface 3.5 mm male. The connector has a straight direction.

Antenna and radio units for small cell applications are steadily shrinking, so it makes sense to also create ever-smaller connector systems for them. Designed to excellently meet the mechanical and electrical needs of small cell products, the new NEX10® is now conquering the market.

3.5 mm coax connectors can be used up to 33 GHz and have low manufacturing tolerances. They are designed for many mating cycles It has an air dielectric interface and closely controlled center conductor support bead providing mechanical interface tolerances similar to hermaphroditic connectors. A 3.5 mm coaxial interface can be mechanically mated with 2.92 mm and SMA connectors, but the connection creates a signal reflection that must be considered.
