MI-171 │ KA-1000
The document describes the MI-171 and KA-1000 Tower Mounted Amplifiers (TMA) designed for deployment in co-located AWS, 1900, and low band systems with wideband antennas. These amplifiers provide internal duplexing across three bands with uplink gain in high bands and a passive Tx/Rx path to a low-band antenna port, optimizing cost and space efficiency.
Features
- Improved base station sensitivity in AWS and 1900 uplink bands.
- Available as twin (4 antenna ports) or quad units (8 antenna ports) for 4x4 or 8x8 MIMO systems.
- Excellent noise figure performance and internal duplexing for multiple bands.
- AISG2.0 compatibility and compact, lightweight design.
Technical Specifications
- Downlink (TX) Path: Passband for PCS is 1930-1990 MHz and for AWS is 2110-2200 MHz with typical insertion loss of 0.5dB and 0.3dB respectively.
- Uplink (RX) Path: Passband for PCS is 1850-1910 MHz and for AWS is 1695-1780 MHz with a gain of 12dB ± 1.0 dB.
- Low Band Bypass Path: Passband is 617-894 MHz with typical insertion loss of 0.2dB.
- Electrical specifications include 50 Ohms impedance and AISG mode operation with a power consumption of less than 4W.
Environmental and Mechanical Specifications
- Operating temperature range from -40ºC to +65ºC with IP67 ingress protection.
- Lightning protection and compliance with EMC and RoHS standards.
- Dimensions and weight vary between twin and quad units, with mounting options for poles or walls.
Ordering Information
- Part numbers and configurations are provided for both twin and quad units, with AISG mode options.
Brand Transition
Microdata Telecom has rebranded to Kaelus, with both part numbers maintained to ease customer transition.

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.
