TWIN TMA 1900/AWS LOWPASS

Designed to be deployed in co-located AWS, 1900 and low band (698-960) systems with wideband antennas, the Kaelus TMA2093 provides internal duplexing in all three bands with uplink gain in the high bands. A passive Tx/Rx path is provided to a low-band antenna port, thereby saving capital expenditure and tower leasing fees.

FEATURES

  • Improved base station sensitivity through gain in the AWS and 1900 uplink bands
  • Excellent noise figure performance
  • Internal duplexing of 698-960MHz signals to be passed to additional ANT ports
  • AISG2.0 compatible, hardware & software configuration using AISG “personality” upload
  • Internal duplexing of AWS and 1900MHz bands
  • DC/AISG bypass onto low band main (optional)

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 can be altered via a field-loadable personality file, contact Kaelus for more information.
DC supply voltage 7.5 to 30V DC, case is DC ground
DC supply voltage via BTS-RF cable DC power can be applied to either port
DC power to be drawn from one BTS port only
DC applied to both BTS ports power will only be drawn from BTS1
DC supply current, normal mode 150 ± 15mA per port (for F00V1)
DC supply current, alarm mode programmable range 150 - 250mA, 220 ± 20mA per port (for F00V1)
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 BTS ports. Both LNAs take DC power from the port with AISG frames or, if DC is present on both ports, both channels supply equal power to the TMA.
DC supply voltage 7.5V to 30V DC
AISG version 2.0 (1.1 optional)
Supply current, AISG mode 300mA @ 7.5V, 85mA @ 30V typical
AISG connector, current rating IEC60130-9, 8-pin female ,< 4A peak, 2A continuous, pin 6
Field firmware upgradable Yes
autosensing function on ant 1 port (tma2093fxxv2 only)
When a valid AISG signal is applied to either of its BTS ports, the TMA2093 (FxxV2) communicates in AISG mode and applies DC/AISG to the ANT1 port. If a low resistance is detected on ANT1 port, DC is disconnected from this port. In CWA mode, the autosensing switch is open and no DC will be passed to the ANT1 port.
Mode of operation Current draw on ANT1 port Assumption “Autosense + Protection” switch status Comment
CWA mode Any Unit in CWA mode Open No DC will be passed on to ANT1 Low band Port
AISG mode Current<4A Device present or open circuit on ANT1, Unit in AISG Mode Close AISG signal (sub-carrier) will be supplied thru to ANT1 Low band Port
AISG mode Current >4A DC short circuit or low DC resistance present on ANT1 port Open Attempts are made periodically to re-connect. The TMA will operate in AISG mode.
