Product overview
The MDOT COMMS A27mini-1400 provides TDD video and data communications for small and medium UAVs, including long-range FPV applications. Its single-band configuration operates at 1335–1475 MHz with 27 dBm (0.5 W) transmit power; both the band and transmit power are customizable. The radio uses 2T2R RF chains, a 10 MHz channel and BPSK or QPSK modulation. It supports P2P and star networking, spectrum sensing and smart frequency selection. Communication distance is approximately 20 km under ideal line-of-sight conditions.
For installation planning, the unit measures 69.5 × 39.5 × 20.5 mm and weighs 90 g. Connections comprise two MMCX RF ports, one power interface, one Ethernet interface, one TTL/RS232 interface and one SBUS/TTL interface. The DC supply range is 9–26 V, with a typical operating point of 12 V at 0.6 A and power draw of ≤7 W. Additional integration parameters include a temperature range of -40 °C to +65 °C, maximum throughput greater than 8 Mbps, latency ≤10 ms and AES encryption.
