Product catalog summary

Product Overview: The Kaelus MI-186 is a TMA (Tower Mounted Amplifier) designed for collocated 700 and 900 MHz systems. It enhances cell uplink coverage by improving the system noise figure, which helps in reducing operational and capital expenditure. The product is compact and lightweight, minimizing visual impact.

Key Features:

Improved base station sensitivity with gain in the 700 and 900 uplink bands.
Internal diplexing on the antenna port for 700 and 900 bands with four antenna ports.
Excellent noise figure performance.
Full AISG operation and RET antenna support, compatible with AISG2.0.

Technical Specifications:

Downlink: Passband varies by model, insertion loss is typically 0.4dB, return loss is a minimum of 18dB, and maximum input power is 200W.
Uplink: Passband varies by model, gain is nominally 12dB, return loss is a minimum of 16dB, and noise figure is typically 1.1dB.
Electrical: Impedance is 50 Ohms, AISG mode is auto-selected on valid AISG 2.0 frames, and power consumption in AISG mode is less than 4W.

Environmental Specifications:

Operating temperature range from -40ºC to +65ºC.
Ingress protection rated at IP67.
Lightning protection for RF and AISG.
MTBF (Mean Time Between Failures) is greater than 1,000,000 hours.

Compliance: The product complies with EMC: EN 301 489-8, Safety: EN 60950, and operational standards ETSI EN 300 019-1-4 class 4.1E.

Mechanical Specifications:

Dimensions are 265 x 150 x 245 mm, and the weight is 12.0 kg.
Finish is powder-coated, and it can be mounted using pole/wall brackets.

Ordering Information: Various configurations are available with different downlink and uplink passbands, connector types, and AISG modes. The part numbers range from MI-18601 to MI-18639, with options for common mode and independent AISG configurations.
