MI-173

TMA TWIN 700/800/900

Designed to be deployed in co-located Low band, 700, 800 and 900MHz systems with wideband antennas, this Tower Mounted Amplifier provides gain in all of the low bands.

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, 800 and 900 uplink
Internal diplexing on the low band port of 700, 800 and 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

Note: in the AISG mode "ONETWO " the multi band TMA is seen as 1 logic units with 2 subunits each and it is only required to connect to one of the two BTS ports. Either port can be used.

Note: in the AISG mode "TWOTWO " the multi band TMA is seen as 2 logic units with 2 subunits each and it is only required to connect to one of the two BTS ports. Either port can be used.

Note: in the AISG mode "TRITWO " the multi band TMA is seen as 3 logic units with 2 subunits each and it is only required to connect to one of the two BTS ports. Either port can be used.
