2.2-5 male screw 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 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 2.2-5 male screw 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 2.2-5 male screw 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 2.2-5 male to interface 3.5 mm male. The connector has a straight direction.

The 2.2-5 connectors are perfect for small cell / distributed antenna systems and have been designed to meet the latest requirements in terms of size, ruggedness, performance and other parameters of radio frequency signal transmission. The small footprint supports the use of smaller components, reduces the risks associated with assembling devices without care, and provides excellent electrical performance.

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.

The screw connection, especially when mounted with a suitable torque wrench, provides the strongest hold and a constantly secure fit of the cable. In addition, the center slots in the contacts provide high contact pressure between the cable and the connector for optimum conductivity and signal strength.
