KA-1002
The document outlines the features of the Kaelus B41 TDD TMA KA-1003, which is designed for improved base station sensitivity at 2500MHz and is suitable for 5G NR signals. It supports full AISG operation and RET antenna, and is compact for minimal visual impact. The device can be configured for 2x2 or 4x4 MIMO.
Band B41 (2500MHz)
Downlink: Passband of 2496-2690MHz, insertion loss of 1.2dB typical, return loss of 18dB minimum, and maximum input power of 40W per channel.
Uplink: Passband of 2496-2690MHz, gain of 12dB, return loss of 18dB minimum, bypass return loss of 18dB minimum, bypass loss of 1.4dB typical, noise figure of 1.6dB typical, and output IP3 of +28dBm typical.
Impedance is 50 Ohms. The AISG mode of operation requires a DC/AISG signal applied to the AISG IN port to power the Low Noise Amplifiers (LNA) in the uplink path, with each LNA controlled by its sub-unit number. The DC supply voltage ranges from +9V to +30V DC, and it supports AISG versions 2.0/3.0.
The device operates within a temperature range of -40ºC to +65ºC and has an ingress protection rating of IP67. It offers lightning protection with RF and AISG tolerances of ±5kA maximum. The MTBF is 1.0Mh. Compliance includes EMC: EN 301 489-50, Safety: IEC/EN 62368-1, and Operation: ETSI 300 019-1-4, Class 4.1E.
The dimensions for 2x2 configuration are 180x297x61 mm and for 4x4 configuration are 180x297x96 mm. The weight is 4.0 kg for 2x2 and 6.8 kg for 4x4. The finish is NCS 1502-R, and it includes a pole/wall bracket for mounting.
The document provides part numbers for different configurations and optional features, including connector types and AISG modes.
