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 voltage 8.5V to 30V DC, case is DC ground
DC supply voltage via BTS-RF cable Through BTS connectors
DC supply current, normal mode 150 ± 20mA per port, 1.3W @ 8.5V, 4.5W @ 30V typical
DC supply current, alarm mode programmable range 220 ± 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.
DC supply voltage +8V to +30V DC
AISG version 2.0 (1.1 optional)
Supply current, AISG mode 220mA @ 8.5V, 70mA @ 30V typical
Voltage drop, BTS to AISG port 1.5V maximum at 2A
Power consumption, AISG mode 1.9W @ 8.5V, 2.1W @ 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 (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.
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
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
AISG mode Current >4A DC short circuit or low DC resistance present on ANT1 port Open Attempts are made periodically to re-connect. TMA2094FxxVx-1 will operate in AISG mode.
