MI-165

MI-165

TMA TWIN 800/900

Designed to be deployed in collocated 800 and 900 systems, the Kaelus MI-165 enhances cell uplink coverage in 800 and 900 through improved system noise figure, thereby saving operational and capital expenditure.

FEATURES

  • Improved base station sensitivity through gain in the 800 and 900 uplink
  • 4 Antenna ports
  • Excellent noise figure performance
  • Full AISG operation and RET antenna support, AISG2.0 compatible
  • Small and light for minimum visual impact

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. Please contact Kaelus for more information.
DC supply voltage +9 to +15V DC
DC supply current, normal mode 165mA @ 12V
DC supply current, alarm mode 320mA max
aisg mode of operation (auto selected on valid aisg 2.0 frames)
AISG signals can be applied to the BTS ports. The TMA unit switches to AISG mode when valid frames are detected on either port. Each LNA is controlled uniquely by its sub-unit number.
DC supply voltage 24 V DC nominal (+9.0V to +31V DC)
