Broadband Combiner Box, KM-99N 8 x 4 Combiner for Neutral Host In Building Systems 698 - 2,700 MHz, includes Output Test Port
Advanced Data Input bands for Cellular & LTE: 700/800/900 & 1800/1900/UMTS to 2700 MHz 8 Inputs to 4 Combined Outputs High Reliability, RoHS Lossless Concept, Guaranteed PIM Test port to monitor sum of outputs
These broadband RF Combiner Boxes have been designed to meet the neutral host needs of in-building systems, with low passive intermodulation (PIM). The system combines up to 8 wireless carriers in the operating bands to 4 multiple antenna feeds or distribution cables. One quarter of each input appears on each of the four outputs, with a dissipated path loss of less than 0.5 dB. Typical isolation between inputs in the same band is 22 - 24 dB, between bands 58 dB. In this KM-99N a monitor of the sum of all outputs is provided, a useful way of assessing performance without the need for system disconnection. Different upper and lower bands and any or all of the connectors are available in 7-16 mm DIN to order. (09/10)
