The Kaelus twin 2600MHz tower mounted amplifier has been designed to operate in LTE2600MHz networks and provides gain in the uplink with excellent noise figure performance.


  • Improved base station sensitivity through gain in the 2600 uplink band
  • Excellent noise figure performance
  • Fail safe bypass mode and full lightning protection
  • AISG 2.0 compatible, fully software upgradable

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 supply voltage via BTS-RF cableEach BTS port powered individually (programmable)
DC supply current, normal mode100 ± 20mA per port (F00V1 version, programmable)
0.85W @ 7.5V, 3W @ 30V typical
DC supply current, alarm mode180 ± 20mA per port (F00V1 version, programmable)
2.7W @ 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 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.
DC supply voltage+7.5V to +30V DC
AISG version2.0 (1.1 optional)
Supply current, AISG mode200mA @ 7.5V, 55mA @ 30V typical
AISG connector, current ratingIEC60130-9, 8-pin female, < 4A peak, 2A continuous, pin 6
