AirPro-1: RF Transceiver

Airpro-1

Air Pro-1 digital data link system specifically designed for miniature and micro-sized UAVs and other unmanned platforms with strict SWaP constraints. The Air Pro-1 provides full duplex digital communication, using RF transceiver to reduce the form factor of the device.

The modulation scheme used is QPSK, maintaining high data link performance with a high fade margin. This feature makes it ideal for tactical unmanned systems with limited power budgets. The Air Pro-1 can downlink real-time serial data and LAN, information from a wide range of sensors. With high spectral efficiency and with encrypted data.

  • Integrated with Wide band RF Transceiver including configurable high speed ADCs and DACs
  • Supports time division duplex (TDD) and frequency division duplex (FDD) operation.
  • The receiver (Rx) subsystem includes independent automatic gain control (AGC) Independent and Manual Gain control (MGC).
  • Easy to configure and generate customized waveforms based on end application
  • FPGA has rich resources to implement waveform generation and signal processing.
