SPINNER Combining Units for best radio frequency networks performance
Combining units are essential components in radio frequency networks, used to merge signals from multiple sources or split signals into multiple paths while maintaining signal integrity. All combiners work in bi-directional mode and can therefore be used to combine and split the transmitted and received signals.
The 7-way manifold combiner band 4/5 DTV/ATV 450 W output power 50 W NB input ensures optimal performance for signal transmission between transmitter and antenna in broadcast stations.
A manifold combiner is a device designed to combine multiple input signals into a single output. This is particularly useful in environments where space efficiency and signal integrity are paramount. Manifold combiners are used to streamline the handling of signals from different sources, facilitating a cleaner and more efficient distribution of signals within the network infrastructure. This makes them essential for complex systems where multiple channels need to be managed effectively and without interference.
Manifold combiners are usually designed as 2- or 3-way combiners and require a minimum spacing of one channel or one DAB block in between.
SPINNER’s Manifold Combiners excel in reliability, performance, and adaptability. Our products are recommended because they provide a flexible solution for both indoor and outdoor mobile communication networks. Whether enhancing in-
building coverage or expanding network capacity, SPINNER’s Manifold Combiners offer a reliable backbone for seamless wireless communication.
Transmitters can be isolated from each other by connecting a bandpass filter to each output. To achieve good matching for the operating channels, the outputs of these filters must be connected via a suitable matching network.
Frequency changes or extensions are difficult to accomplish with combiners of these kinds because the matching networks have to be optimized for the new frequencies.
Outstanding RF characteristics, best possible passive intermodulation and VSWR
The 7-way manifold combiner band 4/5 DTV/ATV 450 W output power 50 W NB input enables you to transmit high-frequency signals reliably and flawlessly with optimum protection of your sensitive equipment in a power range up to 50 W (per input) with maximum passive intermodulation (IM3).
The port path designation regarding main line and probe is as follows: Port 1, 2, 3, 4, 5, 6, 7: narrow band input, Port 8: output
It supports the use of the following frequency bands : Band 4/5
The positive characteristics are briefly summarised: 4 RU compact design as 19" slide-in unit, suitable for analogue and digital TV, applicable within the whole UHF range, for 6, 7 and 8 MHz channel bandwidth, temperature compensated.
The N-coaxial connectors were named after their inventor Paul Neill, who developed this standard for RF connectors in 1942. Often, however, the name also relates to the Navy Connector. Type N connectors can be used at frequencies up to 11 GHz, high-precision types up to 18 GHz. It is typically used in mobile communication applications with demanding mechanical and electrical requirements. SPINNER exclusively manufactures connectors with non-slotted outer conductor contacts and a special sealing profile in the connector head instead of the flat seal disk, specified by IEC or CECC. This ensures the most reliable sealing function.
The product offers a transition from interface N female to interface N female.
