SPINNER provides after sales service to manage the frequency changes induced by 700 MHz clearance projects. The planning of modifications can be done without site surveys using detailed documentation prepared in the factory.The SPINNER staff does everything possible to assist the customers, even in unusual situations.

The SPINNER low PIM switch - a double-pole, double-throw switch has revolutionized equipment testing. It lets you tap potentially enormous savings on the order of about 90% compared to conventional methods. If you want to use a switch in a calibrated test system and need it to keep working perfectly through hundreds of thousands of cycles without requiring any maintenance, there is really only one choice: the SPINNER low PIM switch.

With SPINNER you select exactly the jumpers that you need. You decide on the types and lengths of the cables and pick out the connectors. A few days later, you receive a package containing exactly what you ordered. Every mobile communication network is structured the same way. But the equipment and local conditions vary from site to site. To make sure it works well, the prerequisites include technically excellent products, short paths, and no unnecessary transitions (to reduce PIM).

SPINNER has introduced a new family of low PIM DC-breaks. Built with outdoor protection IP 67 these DC breaks are extremely durable, even under tough environmental conditions. With a broad frequency range of 380 to 2,700 MHz, -160 dBc IM3 and with separated inner and outer conductor, most mobile communication scenarios are featured. To make them a solution for today and tomorrow they are built with 4.3-10, 7-16 and N interfaces.

The saving potential of SPINNER’s low PIM switches in RF testing environments is immense. They spare you the hassle of undocking and re-docking measurement cables when performing different measurements on the same DUT. Technically speaking, these are DPDT switches with two parallel-switching inputs and outputs. They are available with 7-16 and 4.3-10 connectors and specified for -165 dBc (typ. -170 dBc).

SPINNER GmbH offers its customers the latest developments in the field of rotating, contactless signal and data transmission by means of capacitive rotary transmitters. Compared to solutions with slip rings, these rotary transmitters are independent of the rotational speed and are maintenance-free. Possible applications can be found in industrial plant engineering, stage engineering, in wind power plants right through to non-destructive material testing systems.

The new second edition of SPINNER’s Air Traffic Control Rotary Joints catalogue covers all rotary joints for civil and military ATC radars. This edition reflects the latest developments for this demanding market with high reliability.  Starting from 3 channels up to 9 channels, S and L-Band solutions are available from Europe’s leading system house of rotary joints.  Customized solutions used for ATC Radar applications can be made available on short notice.

SPINNER’s low PIM attenuator reduces cost by ensuring much more flexibility during installation processes. The low PIM attenuator can be adjusted between 15 and 30 dB and performs with -160 dBc/-165 dBc in mobile carrier frequencies. First DAS outdoor installations have proven to save up to 90% of time during power adjustment. Site and in-building installations will be much faster and more efficient due to the flexibility provided by SPINNER’s low PIM attenuator.

Due to its innovative design, the dielectric waveguide SPINNER EasySnake combines the flexibility of a conventional RF test cable with the excellent low-loss transmission characteristics of a classic waveguide system, initially for the frequency range from 75 to 110 GHz. The extraordinary appearance of the SPINNER EasySnake catches the eye, as the waveguide is composed of individual jointed segments that allow free movement of the line.
