TMA2043F1V1-1

TWIN TMA AWS, LOWPASS

Designed to be used at co-located 700MHz and AWS sites, the Kaelus TMA2043 provides internal diplexing of the two bands. External diplexers and feeders are no longer required, resulting in decreased hardware costs, environmental impact and tower licensing fees.

POWER SUPPLY AND ALARM (CURRENT WINDOW ALARM MODE, DEFAULT)

CWA is the default TMA operating mode and can be configured to specific customer requirements. The TMA is configured so that each BTS port is individually powered and monitored. Each 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
DC supply	Through BTS connector
DC supply current, normal mode	100 ± 20mA per port
DC supply current, alarm mode	200 ± 30mA per port

POWER CONSUMPTION

Normal operation	0.85W @ 7.5V, 3W @ 30V typical
Alarm mode	3W @ 15V per port typical

AISG MODE OF OPERATION (AUTO SELECTED ON VALID AISG 2.0 FRAMES)

AISG signals can be applied to either BTS0 or BTS1 port. The TMA unit switches to AISG mode when valid frames are detected on one of the BTS ports. The TMA unit is DC powered (common feed for both channels) from the port supplying the AISG frames.
DC supply voltage	7.5V to 30V DC, case is DC ground
AISG version	2.0 (1.1 optional)
Supply current, AISG mode	200mA @ 7.5V, 65mA @ 30V typical
Voltage drop, BTS to AISG port	1.5V maximum at 2A
Power consumption, AISG mode	1.5W @ 7.5V, 2W @ 30V typical
AISG connector, current rating	IEC60130-9, 8-pin female / < 4A peak, 2A continuous, pin 6
