2.92 mm female to RUG-2.4 mm female DC-44 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 2.92 mm female to RUG-2.4 mm female DC-44 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 2.92 mm female to RUG-2.4 mm female DC-44 GHz precision adapter enables you to reliably transmit radio-frequency signals in the frequency range from DC to 44 GHz.

The adaptor offers a transition from interface 2.92 mm female to interface 2.4 mm female. The connector has a straight direction.

The 2.92 mm coaxial connector is a reliable connector system that works up to approx. 40 GHz and is used in RF measurement laboratories, on high power components, calibration and verification standards. It is also known as a Type-K connector. A 2.92 mm coax interface can be mechanically mated with 3.5 mm and SMA connector systems, but the connection creates a signal reflection that must be considered. It was the predecessor of the 1.85 mm connector size. Compared to the 3.5 mm connector system, the 2.92 mm interface has a shorter inner conductor pin that allows the outer conductor to be aligned before the inner conductor makes contact. Therefore, the 2.92 mm connector is less susceptible to damage in industrial use.

The coaxial 2.4 mm connector is also known as the Type-Q connector. 2.4 mm coax connectors are particularly suitable for use in radio-frequency test and measurement laboratories for frequencies up to approx. 60 GHz. They are designed with excellent characteristics and tight tolerances over the entire specified frequency range.

RF characteristics

Number of interfaces:
Interface type:
2.92 mm female (50 Ω) per IEEE Std 287
2.4 mm female (50 Ω) per IEEE 287
Interface type remark:
Port 1: In preparation of the upcoming new version of the IEEE Std. 287 the adaptor is defined for a pin diameter of 0.927 mm. Usage with male connectors with pin diameters of 0.914 mm results in an increase of the reflection factor magnitude of typically 0.02.
Port 2: ruggedized by enlarged thread
