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.
