TMA2092F02V3-2A

TMA2092F02V3-2A

TWIN TMA 700H, LOWPASS

Designed to be deployed in co-located 700 and 850MHz networks the Kaelus TMA2092 provides gain in the 700MHz uplink plus a low loss 850MHz bypass. Internal duplexing of the two bands minimizes hardware costs and the number of components at the top of the tower.

FEATURES

  • Improved base station sensitivity through excellent noise figure performance and linearity
  • AISG 2.0 compatible, fully software upgradable using AISG "personality" upload
  • Suitable for 10MHz LTE signals
  • Rejection of the North American public safety band rejection allows co-location
  • AISG/DC pass to BTS1 antenna port

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 generic personality (F00Vx) is configured so that both channels are independently powered and monitored via their respective BTS port. The BTS port sinks additional current to indicate an alarm state in its uplink path. The autosensing switch is open in CWA mode and no DC is passed to ANT1. Normal operating and alarm current values are configured independently via a field-loadable personality file. Please contact Kaelus for more information.
DC supply voltage8.5 to 30V DC, case is DC ground
DC supplyEach BTS port powered individually (programmable)
DC supply current, normal mode185mA maximum. 150mA per port typical
DC supply current, alarm mode220 ± 20mA per port
aisg mode of operation (auto selected on valid aisg 2.0 frames)
AISG signals can be applied to either of the R1/R1 AISG IN ports. The TMA unit switches to AISG mode when valid frames are detected on one of the R1/R1 AISG IN ports, both LNA’s 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.
DC supply voltage+8.5V to +30V DC
AISG version2.0 (1.1 optional)
Supply current, AISG mode300mA @ 8.5V, 100mA @ 30V typical
AISG connector, current ratingIEC60130-9, 8-pin female, < 4A peak, 2A continuous, pin 6
Field firmware upgradableYes
AISG pass through to antenna portYes
autosensing function on +r1/+r1 aisgout port (tma2092fxxv3 only)
When a valid AISG signal is applied to either of its R1/R1 AISG IN ports, the TMA2092F02V3 enters AISG mode and applies DC/AISG to the +R1/+R1 AISGOUT port. If a low resistance is detected, DC/AISG is subsequently disconnected from the +R1/+R1 AISGOUT port. In CWA mode, the autosensing switch is open and no DC is passed to the +R1/+R1 AISGOUT port.
