an advanced high power
long range broadband COFDM
communication system for UAV



pMDDLRadio is an advanced high power long range broadband COFDM communication system for UAV. Based on the new Microhard pMDDLxxxx, it provides the bandwidth and range needed for complex data intensive UAS applications. Designed to be all-in-one solution: simultaneous transmission of full HD video and autopilot control \ telemetry data. The board has a system controller for open platform design. Available in three versions: OEM module with matching connectors; module in rugged aluminium enclosure; module in enclosure with external 10W (25W) BDA amplifiers for ultra long range communication (40 - 100 miles depending on the antennas and tracking system availability).



  • Military connectors: data&power - Harwin M80; RF - Hirose
  • RF channels outside the standard WiFi frequency band. MIMO pMDDLxxxx versions are available for 2350, 2450, 2550 MHz bands. pDDLxxxx version available for 900, 1800 (by special order), 2450 MHz bands
  • Dual diversity receiver / dual antenna ports in the configuration with Microhard pDDLxxxx or dual transmitter and receiver / dual antenna ports in the configuration with Microhard 2x2 MIMO pMDDLxxxx
  • 1W RF output (typical range with skew planar wheel antennas is 6 miles, longer range is available using high gain antennas / RF amplifiers / automatic tracking antennas)
  • Output power software select from 7 dBm to 30 dBm
  • Up to 25 Mbps Throughput @ 8 MHz channel (-78 dBm)
  • Up to 2 Mbps IPerf Throughput @ 4 MHz channel (-102 dBm)
  • Supported external RF amplifiers with automatic direction detection. Available control Tx / Rx Switching
