Broadband Short-Haul Control Station Combiner, 40-960 MHz, 4 Channel
These multi-channel combiners provide frequency-agile operation across their entire frequency range. Short-Haul Control Station Combiners may be used to reduce the number of antennas required on a communications site whilst also ensuring that predictable radio-to-radio isolation is maintained at all times – irrespective of individual radio’s Tx or Rx operating mode or antenna isolation characteristics.
Short-Haul Control Station Combiners provide fixed isolation between radio units using power attenuators and signal combining techniques. The result is higher per channel insertion losses than standard Control Station Combiners. In applications where the radios units are to be operated in close proximity to the network’s base site, this additional insertion loss ensures the base site equipment’s receivers are not overloaded, and the Control Station radio’s receivers are similarly not overloaded by the base site’s transmitters. The combining capabilities of these models can significantly reduce tower clutter and loading, simplify cabling installation and reduce deployment costs at Control Center facilities.
Models are broadband and cover the entire 40-960MHz bandwidth, in standard configurations of 4, 8 and 16 channels. Configurations for use with up to 128 channels (and beyond) are also available.
