Product overview
The MDOT COMMS A33-1400 is a single-band TDD communications unit for integrated video and data transmission. Its 2T2R RF architecture provides two SMA ports, with transmit power specified as 33 dBm (2 W). Both transmit power and the 1335–1475 MHz operating band are customizable. The link offers 10 / 20 MHz channel bandwidths and BPSK, QPSK, 16QAM and 64QAM modulation, alongside AES encryption. Maximum throughput is greater than 20 Mbps and latency is ≤10 ms; the approximately 50 km communication distance applies under ideal line-of-sight conditions.
The unit measures 85.2 × 69.2 × 24.6 mm and weighs 220 g, defining its physical space and mass requirements for integration. Its connections comprise one power interface, one Ethernet interface, two TTL/RS232 interfaces and one SBUS/TTL interface, in addition to the two SMA RF ports. Supply input is DC 9–26 V, with a typical supply of 12 V at 2.1 A and power draw of ≤25 W. The temperature range is -40 °C to +75 °C. Spectrum monitoring, smart frequency selection and P2P, star and Mesh topologies provide the specified networking options.
