Designed to be deployed in co-located AWS & WCS systems with wideband antennas, the Kaelus TMA provides internal diplexing and gain in both bands while allowing 700/850 services to pass through to a separate antenna, thereby saving hardware costs


  • Improved base station sensitivity through gain in AWS and WCS bands
  • High linearity and low noise performance; Bypass provided for 700/850MHz services
  • Hardware and software configuration using AISG “Personality” upload
  • Fail safe bypass mode with lightning protection

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 8.5 to 30V DC, case is DC ground
DC supply Each BTS powered individually (programmable)
DC supply current, normal mode 200 ± 20mA per port (programmable)
DC supply current, alarm mode 300 ± 30mA per port(programmable)
aisg mode of operation (auto selected on valid aisg 2.0 frames)
AISG signals can be applied to either BTS1 or BTS2 ports. The TMA2116FxxVx-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 TMA2116FxxVx-1.
DC supply voltage +8.5V to +30V DC
AISG version 2.0 (1.1 optional)
Supply current, AISG mode 400mA @ 8.5V, 120mA @ 30V typical
