MI-127

Product catalog summary

Overview: The Kaelus MI-127 is designed to enhance cell uplink coverage in 1800 and 2100 MHz systems by improving the system noise figure, which helps reduce operational and capital expenditure. It features improved base station sensitivity, internal diplexing, excellent noise figure performance, and full AISG operation with RET antenna support.

Technical Specifications:

Downlink: Passband for 1800 MHz is 1805-1880 MHz and for 2100 MHz is 2110-2170 MHz. Insertion loss is 0.5dB typical for 1800 MHz and 0.3dB typical for 2100 MHz. Maximum input power is 200W.
Uplink: Passband for 1800 MHz is 1710-1785 MHz and for 2100 MHz is 1920-1980 MHz. Gain is 12dB with a noise figure of 1.4dB typical for 1800 MHz and 1.3dB typical for 2100 MHz.
Electrical: Impedance is 50 Ohms. DC supply voltage ranges from +9 to +15V DC with a normal mode current of 165mA at 12V.

AISG Mode of Operation: The TMA unit switches to AISG mode when valid AISG 2.0 frames are detected. Power consumption in AISG mode is less than 4W.

Environmental Specifications: The unit operates in temperatures ranging from -40ºC to +65ºC and has an ingress protection rating of IP67. It complies with EMC, safety, and operational standards.

Mechanical Specifications: Dimensions are 224 x 109 x 209 mm, and it weighs 6.7 kg. It is designed for pole or wall mounting.

Ordering Information: Various configurations are available with different AISG modes and connector types, such as 7/16 (F) and 4.3-10 (F).
