TMA2050FxxV1-1
GSM900 Part Band, Twin AISG TMA
Designed to be used at co-located 850MHz and 900MHz sites,
the Triasx TMA2050 provides rejection of the 850MHz downlink
frequencies while amplifying the 900MHz thereby removing the
need for external 900MHz filtering.
PRODUCT FEATURES
-
Part band GSM900 with rejection below 890MHz,
ideal for co-located 900 and 850MHz networks
Twin 900MHz TMA unit with high linearity and
low noise figure performance
-
Hardware and software configuration using AISG
personality upload
High reliability with lightning protection and
bypass mode

Current flow is possible only in the direction BTS
towards AISG, with 1.1 Volt drop typical at 2 Amp.
Diode blocking between ports
| Current Alarm Mode
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.
Normal operation DC supply current, per port (Generic)
100mA typical, 120mA max.
Alarm Mode, DC supply current, per port (Generic)
180mA typical
| AISG Mode (auto selected on valid AISG frames)
AISG signals can be applied to either BTS port. The TMA switches to AISG mode when valid frames are detected on
one of the ports. The TMA is DC powered from the BTS port supplying the AISG frames although if DC is present on
both ports then 20 – 120mA is drawn on the non-AISG port.
AISG Version

DC Supply Current
