MI-175

TWIN TMA 700/900

Designed to be deployed in collocated 700, 900 systems, the Kaelus MI-175 enhances cell uplink coverage in 700, 900 through improved system noise figure, thereby saving operational and capital expenditure.

Microdata Telecom rebranding to Kaelus!
Microdata Telecom and Kaelus have had combined operations since Oct 2019 when Microdata acquired Kaelus. We strongly believe that by operating under one global brand we will clarify our strengthened position in the telecom market and from January 18th 2021, we are unifying the brands to Kaelus.

FEATURES

  • Improved base station sensitivity through gain in the 700, 900 uplink
  • Internal diplexing on the high band port of 700,900 bands: 2 Antenna ports
  • Excellent noise figure performance
  • Full AISG operation and RET antenna support, AISG2.0 compatible
  • Small and light for minimum visual impact

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 voltage24 V DC nominal (+9.0V to +31V DC)
AISG version2.0
Power consumption, AISG mode< 4W
AISG connector, current ratingIEC60130-9, 8-pin female, 1.6A
