MI-190
MI-190
The Kaelus MI-190 is designed to enhance cell uplink coverage in PCS and AWS systems by improving the system noise figure, which helps reduce operational and capital expenditure. Key features include improved base station sensitivity, internal diplexing on antenna ports, excellent noise figure performance, full AISG operation, and a compact design for minimal visual impact. It is available in twin or quad configurations.
- Downlink: PCS passband is 1930 - 1990MHz with 0.5dB typical insertion loss; AWS passband is 2110 - 2200MHz with 0.3dB typical insertion loss. Both have a return loss of 20dB typical and 18dB minimum, with a maximum input power of 200W.
- Uplink: PCS passband is 1850 - 1910MHz; AWS passband is 1695 - 1780MHz. Gain is 12dB +/- 1dB typical, with a return loss of 16dB and a noise figure of 1.3dB typical for PCS and 1.1dB typical for AWS.
- Electrical: Impedance is 50 Ohms. AISG mode is auto-selected on valid AISG 2.0 frames, with a DC supply voltage of 24 V DC nominal and power consumption in AISG mode of less than 4W.
The device operates within a temperature range of -40ºC to +65ºC and has an ingress protection rating of IP67. It has a mean time between failures (MTBF) of over 1,200,000 hours and complies with EMC, safety, and operational standards.
The twin configuration dimensions are 258 x 58 x 344mm, weighing 6.5kg, while the quad configuration is 258 x 109 x 344mm, weighing 11kg. Both configurations are powder-coated and can be mounted using pole/wall brackets.
Various part numbers are available for different configurations, with options for AISG modes and connector types. The TMA can be identified as one or two logic units with subunits.
