Operation
Interface 1900 band MIMO BTS Tx/Rx or 2 SISO BTS Tx/Rx ports with Simplex DAS Independently adjustable Tx and Rx levels High Reliability, RoHS compliant Low PIM, High Isolation Standard 2RU EIA Rack (3.5”)
This DAS Carrier Conditioner, KM-55N, is designed to inter-
face either a single MIMO or 2 SISO Tx/Rx signals in the 1900
MHz PCS frequency range, with a simplex MIMO or simplex SISO
DAS system.
It allows independent level adjustment of the Tx and Rx
elements of the wireless signal, once the signal is already split
into Tx and Rx paths.
The unit first separates each of the Tx/Rx inputs into Tx
and Rx paths using a duplexer in both Leg A and Leg B. Each ofthe Tx outputs are then attenuated by a fixed 15dB attenuator
before being fed to a 0-30 dB level adjustment to set optimum
DAS performance. Each DAS Rx signal is fed to the Rx port of
the duplexers via a similar level adjustment.
If the system uses 2 SISO signals they may be combined
with a supplied external jumper to feed a common DAS in both
the Tx and Rx paths.
Similar systems can be supplied for other wireless bands,
using appropriate duplexers. (01/13)
