Product overview
The MDOT COMMS A27-1400 provides a TDD link for video and data, with higher-order modulation supporting HD video return. Its single-band radio operates at 1335–1475 MHz, with customizable operating band and transmit power. The 2T2R architecture supports 10 / 20 MHz channels and BPSK, QPSK, 16QAM and 64QAM modulation. Maximum throughput is greater than 20 Mbps and latency is ≤10 ms. AES encryption, real-time spectrum monitoring and intelligent frequency selection within 140 MHz accompany support for P2P, Star and Mesh networking.
The full-size module measures 80.2 × 60.7 × 17 mm and weighs 100 g, defining its physical integration envelope. Connections comprise two MMCX RF ports, one power interface, one Ethernet interface, one TTL/RS232 interface and one SBUS/TTL interface. Supply requirements are DC 9–26 V, typically 12 V @ 0.8 A, with power draw ≤10 W. The temperature range is -40 °C to +75 °C. Communication distance is approximately 20 km under ideal line-of-sight conditions.
