Connectors & Adaptors

Rosenberger offers non-magnetic versions of standard connector interfaces including Multiport-Mini-Coax, QMA and SMP. All materials and platings are non-magnetic which is mandatory in certain environments. They are widely used, for example, by the medical industries in MRI (Magnetic Resonance Imaging) equipment as well as in aerospace and other specialized industrial applications. The non-magnetic product range includes standard coaxial connector and cable assemblies. Customized solutions are available upon request.

Rosenberger has introduced the P-SMP series of Power/RF coaxial connectors, combining all the space saving advantages of SMP connectors with the high performance of SMA connectors. Unlike SMA and QMA solutions, minimum board-to-board distances of 12.6 mm can be realized by using bullets in different lengths. Furthermore, P-SMP connectors are designed for high power loads, up to 200 W @ 2.2 GHz continuous power, and can handle high frequencies up to 10 GHz. Typical applications therefore include board-to-board connections in base stations or board-to-cable connections in power amplifier filter units.

Based on the SMA connector standard, Rosenberger QMA connectors are designed for applications up to 18 GHz. The quick-lock mechanism enables easy and reliable connections in the tightest of spaces – primarily in mobile base stations – and 10 times faster compared to SMA offerings. Packing density is also superior to SMA due to the minimum pitch and toolless connection, dispensing with the need for torque spanners for fastening coupling nuts. Rosenberger offers QMA as standard version and with plastic quick-lock mechanisms in four different color codings. QMA is not intermateable with SMA.

Rosenberger QN coaxial connectors are based on the N connector interface. With a frequency range of up to 11 GHz depending on the connector and cable type, the quick-lock mechanism enables reliable and easy connection, 10 times faster than standard N offerings. Ideal for tight spaces such as those found in mobile base stations, the packing density of QN exceeds that of N connectors due to the minimum pitch and toolless assembly. Torque spanners are not required. QN and standard N connectors are not intermateable.

Rosenberger provides SMA, BNC and TNC reverse polarity connectors. These coaxial connectors are non-standardized versions, offering interfaces similar to the standard but with center contacts and dielectricum reversed; for use with W-LAN routers when safeguarding against the possibility of incorrect component connection.

The interface standardization is in progress.

Rosenberger RPC-1.85 precision connectors – with 50 Ω impedance and 1.85 mm outer conductor diameter – are designed for test & measurement applications up to 70 GHz. Delivering outstanding reliability and repeatability performance they are intermateable with common 1.85 mm series and V connectors as well as with RPC-2.40 connectors. This comprehensive product range is suitable for semi-rigid cables and microwave components and includes cable, panel and PCB connectors, adaptors and test & measurement accessories – including RPC-1.85 calibration kits, cables assemblies, measurement equipment, attenuators, sliding loads and airlines.

Rosenberger RPC-2.40 connectors – high reliability and outstanding repeatability – are designed for precision test & measurement applications up to 50 GHz. With 50 Ω impedance and 2.40 mm outer conductor, they are intermateable with many other 2.40 mm series connectors such as APC-2.40, OS-50, HP-2.40 or RPC-1.85 and V connectors. A wide range of RPC-2.40 cable and PCB connectors, adaptors and interchangeable port connectors is available as well as test & measurement accessories. These include RPC-2.40 calibration kits, test cables and measurement equipment.

applications up to 40 GHz. The shortened male pin and fourfold slotted female center contact allow these high-quality connectors to meet the highest levels of reliability and repeatability performance. RPC-2.92 connectors are intermateable with common 2.92, 3.50, SMA, as well as K connectors.

RPC-N 50 Ω are intermateable with standard N 50 Ω connectors, RPC-N 75 Ω are intermateable with standard N 75 Ω connectors. Rosenberger RPC-N 50 Ω and RPC-7 connector heads are interchangeable using the same bead type.

The Rosenberger RPC-SL series are interchangeable port connector systems for use with test equipment where test ports are frequently mated and re-mated. Under such heavy usage, Rosenberger RPC-SL interchangeable port connectors allow the equipment/device interface to be fully protected from potential damage, avoiding the risk of costly repairs. The RPC-SL port connector includes a panel mounting half and a sexless interface which features two spring-loaded butt contacts. This ensures no wear occurs during mating and eliminates the possibility of accidental damage from mismatching of connector halves. Furthermore, the interface between the panel mount and the adaptor is slotted, preventing the mating faces from rotating and possible damage. The RPC-SL portfolio offers both 26.5 GHz and 40 GHz versions. While adaptors can be interchanged and are available in different connector series, the connector heads in these two ranges are not compatible and can only be used with their own system.

Rosenberger RPC-SP 50 Ω precision connectors are designed for applications up to 22 GHz where quick and reliable interconnects are essential. Intermateable with OSP and BMA connectors, the floating construction allows compensation for axial and radial misalignment while the innovative blind mate self-finding mechanism ensures fast, easy connection and disconnection, bringing significant time and cost reductions. Furthermore, tightening the connection requires no additional tooling. RPC-SP connectors are therefore ideal for use where space is at a premium such as in many rack and plug-in applications. The product range comprises cable, panel and PCB connectors, adaptors to other coaxial connector series, airlines as well as test & measurement accessories such as RPC-SP calibration kits, test cables or measurement equipment (open – short – load).

Rosenberger SLC (Spring Loaded Contacts) are suited to customized designs and frequencies up to 6 GHz. The product portfolio ensures impedance controlled SLC for transmission of RF signals across a diverse range of customized products and applications, such as backplane designs and those requiring a high degree of tolerance compensation between mating partners. Rosenberger SLC connectors and assemblies are therefore a perfect fit for specialized board-to-board applications, hybrid SLC solutions – with a combination of DC, RF signal transmission, power supply and fiber optical lines – as well as SLC cable connectors, board and panel mounted products.
