A full Band 2100MHz tower mounted amplifier the Kaelus TMA2009 provides gain at 2100MHz with a 800/850/900MHz bypass with internal diplexing of these bands on the BTS side of the amplifier. Potentially saving both capital and operational expense the TMA2009 provides the following features and benefits:


  • Twin dual duplex configuration with low frequency bypass perfect for co-located 2100MHz UMTS and 800/850/900MHz systems
  • Improved BTS performance through excellent noise figure performance
  • Hardware & software configurable using AISG “personality” upload

power supply and alarm (current window alarm mode, default)
Current window alarm mode (CWA) is the default TMA operating mode and can be configured to specific customer requirements. The generic personality (F00V1) is configured so that both channels are independently powered and monitored via the respective BTS port. The BTS port sinks additional current to indicate an alarm state in its uplink path. Normal operating and alarm current values are configured independently via a field-loadable personality file, Please contact Kaelus for more information.
DC supply voltage +9 to 30V DC
DC supply current, normal mode BTS0 = 100mA (F5V3 variant)
BTS1 = 100mA (F5V3 variant)
DC supply current, alarm mode 50/50 duty cycle pulsed between 100/160mA (F5V3 variant)
aisg mode of operation (auto selected on valid aisg 2.0 frames)
AISG signals can be applied to either BTS1 or BTS2 ports. The TMA2009FxxV3-1 unit switches to AISG mode when valid frames are detected on one of the BTS ports. Both LNAs take DC power from the port with AISG frames or, if DC is present on both ports, both channels supply equal power to the TMA2009FxxVx-1.

Supply current, AISG mode 80mA at 30V, 155mA at 12V typical
