TMA2068F00V1-1

TWIN TMA 2100

Designed to be deployed in 2100MHz UMTS and LTE systems, the Kaelus TMA2068 provides excellent system performance with full AISG capabilities.

FEATURES

  • Improved base station sensitivity through excellent noise figure performance and gain in the 2100 uplink band
  • Provides rejection in the RX input filter to 1800 and 2600 downlink frequencies
  • Fail-safe bypass mode with full lightning protection
  • Hardware & software configuration using AISG “personality” upload

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
DC supply current, alarm mode180 ± 20mA per port (programmable)
DC supply current, alarm mode programmable range150 - 250mA
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+8.5V to +30V DC
AISG version2.0 (1.1 optional)
