Designed to be used at co-located 700MHz and AWS sites, the Kaelus TMA2072 provides internal diplexing of the two bands. External diplexers and feeders are no longer required, resulting in decreased hardware costs, environmental impact and tower licensing fees


  • LTE ready
  • Provides gain in the AWS path and bypass to 700MHz frequencies
  • Excellent noise figure performance
  • AISG 2.0 compatible, fully software upgradable
  • Full lightning protection and fail-safe bypass mode

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 and are alterable via a field-loadable personality file, contact Kaelus for more information.
DC supply voltage7.5V to 30V DC, case is DC ground
DC supplyThrough BTS connector
DC supply current, normal mode100 ± 20mA per port
DC supply current, alarm mode200 ± 30mA per port (programmable)
Power consumption, normal operation 0.85W @ 7.5V, 3W @ 30V typical
Power Consumption, alarm mode 3W @ 15V per port typical
aisg mode of operation (auto selected on valid aisg 2.0 frames)
AISG signals can be applied to either BTS1 or BTS2 port. The TMA 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 TMA.
AISG version2.0 (1.1 optional)
Supply current, AISG mode200mA @ 7.5V, 55mA @ 30V typical
Voltage drop, BTS to AISG port 1.5V maximum at 2A
Power consumption, AISG mode1.5W @ 7.5V, 2W @ 30V typical
AISG connector, current ratingIEC60130-9, 8-pin female, < 4A peak, 2A continuous, pin 6
