KA-1000TWIN TMA AWS/1900 DUAL BAND WITH LOW BAND BYPASS Designed to be deployed in co-located AWS, 1900 and low band systems with wideband antennas, this Tower Mounted Amplifier provides internal duplexing in all three bands with uplink gain in the high bands. A passive Tx/Rx path is provided to a low-band antenna port, thereby saving capital expenditure and tower leasing fees. 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. The MI-171 and the KA-1000 are the same product but to ease the transition for our customers both Kaelus and Microdata part numbers will be maintained. MI-171: part number under Microdata brand KA-1000: part number under Kaelus brand. • Improved base station sensitivity through gain in the AWS and 1900 uplink bands • Highly integrated unit available as a twin unit (4 antenna ports) or as a quad unit (8 antenna ports) to suit 4x4 or 8x8 MIMO systems • Excellent noise figure performance • Internal duplexing of 617-894MHz signals to be passed to additional ANT ports • Internal duplexing of AWS and 1900 bands © Kaelus 2020.
