Designed to be deployed in co-located AWS & 1900MHz systems with wideband antennas, the Kaelus TMA2066 provides internal diplexing and gain in both frequency bands, thereby saving both operational and capital expenditure


  • Improved base station sensitivity through gain in the AWS and 1900 uplink bands
  • Excellent noise figure performance
  • AISG2.0 compatible
  • Hardware and software configuration using AISG “personality” upload
  • Internal duplexing of AWS and 1900MHz bands
  • Compact, low weight

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 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.
DC supply voltage via BTS-RF cable 7.5V to 30V DC, case is DC ground
Each BTS port powered individually (programmable)
DC supply current, normal mode 150 ± 15mA per port
DC supply current, alarm mode 220 ± 20mA per port (programmable)
DC supply current, alarm mode programmable range 150 - 250mA with 100mA normal operating current
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 version 2.0 (1.1 optional)
Supply current, AISG mode 265mA @ 7.5V, 75mA @ 30V typical
Voltage drop, BTS to AISG port 1.5V maximum at 2A
AISG connector, current rating IEC60130-9, 8-pin female, < 4A peak, 2A continuous, pin 6
Field firmware upgradable Yes
