TMA2094F01V2-1

TMA2094F01V2-1

TWIN TMA 700, LOWPASS

Designed to be deployed in 700, 850/900MHz shared antenna systems, the Kaelus TMA2094 provides gain at the 700MHz uplink band while allowing 850/900 services to pass through to the antenna thereby saving OPEX and CAPEX.

FEATURES

  • Improved base station sensitivity through gain in 700Mhz band
  • Bypass for 850/900 bands with internal diplexing of the 807-960 and 700MHz bands
  • Rejection of digital TV broadcast channels
  • Hardware and software configuration using AISG “Personality” upload
  • Fail safe bypass mode with lightning protection
  • High linearity and low noise performance

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 F01V1 personality 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 via a field-loadable personality file. Please contact Kaelus for more information.
DC supply voltage8.5V to 30V DC, case is DC ground

DC supply current, normal mode150 ± 20mA per port, 1.3W @ 8.5V, 4.5W @ 30V typical
DC supply current, alarm mode programmable range220 ± 20mA per port, 3.3W @ 15V per port typical
aisg mode of operation (auto selected on valid aisg 2.0 frames)
AISG signals can be applied to either BTS1 or BTS2 ports. The TMA2094F01V2-1 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 TMA2094F01V2-1.

Field firmware upgradableYes
autosensing function on ant 1 port (aisg mode only)
When a valid AISG signal is applied to either of the BTS ports, the TMA2094F01V2-1 communicates in AISG mode and applies DC/AISG to the ANT1 port. If a low resistance is detected on ANT1 port, DC/AISG is subsequently disconnected from the ANT1 port. In CWA mode, the autosensing switch is open and no DC will be passed ANT1.
