SPINNER - RF Components for Mobile Communications Networks and Broadcasting Sites

SPINNER is one of the largest manufacturers of RF components for mobile communication networks and broadcasting sites. It can supply coaxial connectors and adaptors, coaxial cable assemblies, low-intermodulation jumper cables and surge protectors.

Coaxial connectors and measuring devices

SPINNER's current product range includes coaxial connectors from 3.5mm through 230mm (SMA through 9in and the respective coupling elements). The main applications are mobile communication, broadcasting and radio links as well as radar and medical technology. The connector series complies with the applicable DIN, CECC or IEC standards.

The range of coaxial measuring devices includes all coaxial loads from 2W through to 50,000W, such as bridge resistors or power absorbers with convection or water cooling. In addition, you will find symmetrical and asymmetrical dry attenuators (5W through 2,000W) as well as directional couplers and filters.

Coaxial cable assemblies

SPINNER specialises in producing coaxial cable assemblies. It offers its customers a broad range of ready-for-use cable assemblies at favourable prices. The product range includes cables of all sizes with various connector types that can also be made to customer-specifications at short notice. Besides mechanical requirements, the specifications can also include high-frequency related parameters such as reflection factor, insertion loss, electrical length, etc.

Jumper cables

SPINNER has more than 12 years of experience in manufacturing low-intermodulation jumper cables. Special connectors and soldered conductors guarantee superior loss and outstanding long-term intermodulation performance even under adverse environmental conditions. All jumpers are automatically tested by highly sensitive measurement equipment to ensure SPINNER delivers the finest products on the market.

Surge protectors

For Tetra systems SPINNER offers surge protectors with a quarter wavelength stub featuring low reflection and excellent protection properties, as well as very compact design. Surge protectors become increasingly important against overvoltage in coaxial transmission systems. It is mainly exposed antennas and masts of mobile communication base stations that are threatened by lightning damage.

Quarter wavelength stubs have proven to be very effective because they divert high currents to ground. Another advantage is the low residual pulse energy lead to the protected side. In addition to the well-known product range for the mobile communication networks GSM900, GSM1800, UMTS and WLAN, SPINNER can now offer a surge protector with a quarter wavelength stub for the Tetra network, too.

The well-designed combination of transformer elements allows us to cut the length of the stub, which would usually have to be about 20cm for the Tetra network frequencies, to one third. The resulting compact shape opens up possibilities of using the protector in locations where low weight is an advantage and where only limited installation space is available.
