Product overview
Hangzhou Mdot Communication Technology Co.,Ltd.’s A37-1400&2200 is a dual-band TDD communication unit for video and data, with 2T2R RF architecture and 37 dBm (5 W) transmit power. It operates across 1335–1475 MHz and 2155–2295 MHz, with customizable bands and transmit power. Its communication distance is approximately 100 km under ideal line-of-sight conditions. Distributed frequency selection across two 140 MHz windows, spectrum monitoring, and multipath and interference resilience support its industrial communication purpose; supported network arrangements include P2P, star, and mesh.
The unit measures 176.7 × 77 × 30.5 mm and weighs 530 g, defining its physical integration space and mass requirement. Connections comprise 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 1.3 A and power draw of ≤36 W. Other specifications include 10 / 20 MHz channel bandwidth, BPSK through 64QAM modulation, AES encryption, greater than 20 Mbps maximum throughput, ≤10 ms latency, and a temperature range of -40 °C to +75 °C.
