TMA2124F03V5-1D

TWIN TMA 1900/AWS/LOWPASS 555-960MHz 6 ANT

NON-DIPLEXED 1900/AWS ANTENNA PORTS

Designed to be deployed in co-located AWS & 1900 networks, the Kaelus TMA2124 provides gain in 1900 and AWS uplink, using independent LNAs per band and per channel. Low loss bypass 555-960MHz signal to low band antennas is also provided.

FEATURES

  • Improved base station sensitivity through excellent noise figure performance and linearity
  • AISG 2.0 compatible, full software upgradable using AISG “personality” upload
  • DC/AISG passthrough to AWS antenna (port 5)
  • AISG OUT connector disabled when AISG device (SBT equipped antenna) present on Port 3 +R1/+R1
  • One AISG subunit per LNA, 4 in total. All fixed gain
  • 555-960 bypass to low band antenna

power supply and alarm (current window alarm mode, default)
Current window alarm mode (CWA) is the default operating mode and can be configured to specific customer requirements. The TMA2124F03V4 is configured so that both channels are independently powered and monitored via their respective BTS port, 7 or 8. 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 +18V DC, case is DC ground
DC supply Each BTS port powered individually
DC supply current, normal mode 200mA per port typical (both ports are powered)
DC supply current, alarm mode 300mA per port typical (both ports are powered)
aisg mode of operation (auto selected on valid aisg 2.0 frames)
AISG signals can be applied to port 7 or port 8. The TMA unit switches to AISG mode when valid frames are detected on either port 7 or 8. All LNAs take DC power from the port with the AISG frames or, if DC is present on both ports, power will be supplied equally between the ports. Each LNA is controlled uniquely by its sub-unit number.
DC supply voltage +7.5V to +30V DC
AISG version 2.0 (1.1 optional)
Supply current, AISG mode 500mA @ 7.5V, 135mA @ 30V typical
AISG connector, current rating IEC60130-9, 8-pin female, < 4A peak, 2A continuous, pin 6
Field firmware upgradable Yes (R951022ATA2.0 Rev 2.9.12)
AISG pass through to antenna port Yes
antenna aisg ook + dc
When DC is applied it is quickly switched through to port 5. If an over-current condition is detected, DC & AISG are disconnected from port 5. If DC remains connected to the load at port 5, DC and AISG are disconnected from the AISG OUT 8 pin connector. If DC is disconnected from port 5, DC and AISG are enabled at the AISG OUT 8 pin connector. If a short circuit is detected at the AISG OUT 8 pin connector, DC and AISG are disabled.
