MI-175
The Kaelus MI-175 TWIN TMA 700/900 is designed to enhance cell uplink coverage in 700 and 900 MHz bands by improving system noise figure, which helps in reducing operational and capital expenditure. Key features include improved base station sensitivity, internal diplexing on high band ports, excellent noise figure performance, full AISG operation, and RET antenna support. The unit is compact and lightweight to minimize visual impact.
- Downlink: Passband varies by model, insertion loss is typically 0.4dB, return loss is 18dB, and maximum input power is 200W.
- Uplink: Passband varies by model, gain is 12dB, return loss is 16dB, bypass return loss is 12dB, bypass loss is 1.7dB, noise figure is 1.1dB, and output IP3 is 25dBm.
- Electrical: Impedance is 50 Ohms, AISG version 2.0, power consumption in AISG mode is less than 4W.
The unit operates in temperatures ranging from -40ºC to +65ºC and has an ingress protection rating of IP67. It offers lightning protection and complies with various EMC and safety standards.
The dimensions are 265 x 147 x 245 mm, and it weighs 11.80 kg. The unit is powder-coated and can be mounted using pole or wall brackets.
Various configurations are available with different passbands and connector types. The TMA can be identified as either one logic unit with two subunits or two logic units with two subunits each.
