TMA2042F1V1-1

TMA 700/AWS

Designed to be used at co-located 700MHz and AWS sites, the Kaelus TMA2042 provides internal diplexing of the two bands. Costly 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 mode is the default TMA operating mode. The BTS port sinks additional current to indicate an alarm state.
DC supply voltage	7.5V to 30V DC, case is DC ground
DC supply	Through BTS connector
DC supply current, normal mode	200 ± 20mA
DC supply current, alarm mode	300 ± 30mA

POWER CONSUMPTION

Normal operation	1.5W @ 7.5V, 6.0W @ 30V typical
Alarm mode	4.5W @ 15V typical

AISG MODE OF OPERATION (AUTO SELECTED ON VALID AISG 2.0 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 unit is DC powered only from the BTS port supplying the AISG frames.
AISG version	2.0 (1.1 optional)
Supply current, AISG mode	200mA @ 7.5V, 65mA @ 30V typical
Voltage drop, BTS to AISG port	0.2V 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
