TMA2053F00V1-1

TWIN TMA 1800/2100

Designed to be deployed in co-located 1800 & 2100MHz systems with wideband antennas, the Kaelus TMA2053 provides internal diplexing and gain in both bands, thereby saving hardware costs.

FEATURES

  • Improved base station sensitivity through gain in the 1800 and 2100 uplink bands
  • Hardware & software configuration using AISG “personality” upload
  • Excellent noise figure performance
  • Internal diplexing of 1800 and 2100MHz bands
  • AISG2.0 compatible
  • 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 (F00) 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 voltage 7.5V to 30V DC, case is DC ground, via BTS-RF cable
DC supply voltage via BTS-RF cable F00 Version: each BTS port powered individually (programmable)
DC supply current, normal mode 150 ± 15mA per port (assumes both ports are powered)
DC supply current, alarm mode 220 ± 20mA per port (assumes both ports are powered)
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.
DC supply voltage 7.5V to 30V DC
AISG version 2.0 (1.1 optional)
Supply current, AISG mode 265mA @ 7.5V, 75mA @ 30V typical
