3.5 mm male push-pull to 3.5 mm female DC-26.5 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 3.5 mm male push-pull to 3.5 mm female DC-26.5 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 3.5 mm male push-pull to 3.5 mm female DC-26.5 GHz precision adapter enables you to reliably transmit radio-frequency signals in the frequency range from DC to 26.5 GHz.

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

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 push-pull connection is quick and easy to loosen and yet provides enough grip and a secure fit. In addition, the center slots in the contacts provide high contact pressure between the cable and the connector for optimum conductivity and signal strength.
