TMA2071F00V1-1

TMA2071F00V1-1

TWIN TMA 850/1900

Designed to be deployed in co-located 850MHz and 1900MHz systems, the Kaelus TMA2071 provides internal diplexing of the different bands saving capital expenditure on costly external diplexers. The TMA2071 has the following features and benefits:

FEATURES

  • Full band 850MHz and 1900 MHz
  • Excellent system performance through high linearity and low noise performance
  • AISG and current dump compatible
  • Compact, low weight and simple to install
  • Fails safe bypass mode with lightning protection
  • Hardware and 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 voltage via BTS-RF cable7.5V to 18V DC, case is DC ground
DC supply current, normal mode250 ± 30mA per port
DC supply current, alarm mode programmable range350 ± 30mA per port
Power consumption, normal operation 1.9W @ 7.5V, 4.5W @ 18V typical
Power Consumption, alarm mode 5.25W @ 15V per port typical
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 ports. The TMA unit is DC powered only from the BTS port supplying the AISG frames.
AISG version2.0 (1.1 optional)
Supply current, AISG mode420mA @ 7.5V, 110mA @ 30V typical
Voltage drop, BTS to AISG port 1.5V maximum at 2A
