Product overview
The MDOT COMMS A46-1400 provides a single-band TDD link for video and data, with 2T2R RF chains and 46 dBm (40 W) transmit power. Its 1335–1475 MHz operating band and transmit power are customizable. Communication distance is approximately 300 km under ideal line-of-sight conditions. Network options include point-to-point, star and Mesh arrangements, supported by spectrum monitoring and smart frequency selection. The radio offers 10 / 20 MHz channel bandwidths, BPSK through 64QAM modulation, AES encryption, maximum throughput above 20 Mbps and latency of ≤10 ms.
Physical integration requires space for a 180 × 80 × 30 mm unit weighing 900 g. Connections comprise two SMA RF ports, one power interface, two Ethernet interfaces, two TTL/RS232 interfaces and one SBUS/TTL interface. Electrical integration requires a DC 24–30 V supply, with a typical operating point of 28 V at 6.5 A and power draw of ≤182 W. Its temperature range extends from -40 °C to +75 °C, defining the stated thermal envelope for installation.
