Product overview
The MDOT COMMS A37-1400 is a single-band TDD communications unit for carrying video and data in long-range UAV and fixed-site installations. Its 2T2R radio architecture operates at 1335–1475 MHz with 37 dBm (5 W) transmit power; both the band and transmit power are customizable. It supports P2P, star and Mesh networks, with spectrum monitoring and smart frequency selection. Communication distance is approximately 100 km under ideal line-of-sight conditions. Channel bandwidth choices are 10 and 20 MHz, with BPSK, QPSK, 16QAM and 64QAM modulation.
For physical integration, the unit measures 162.9 × 76.9 × 25.2 mm and weighs 350 g. Its connection configuration comprises two SMA RF ports, one power interface, two Ethernet interfaces, two TTL/RS232 interfaces and one SBUS/TTL interface. Electrical integration requires DC 22–30 V, with a typical operating point of 28 V at 1.1 A and power draw of ≤32 W. The temperature range is -40 °C to +75 °C. Communications specifications include throughput above 20 Mbps, latency of ≤10 ms and AES encryption.
