In recent years, unmanned aerial vehicle (UAV) has gained unprecedented attention and development in the world, Especially micro UAV, with its light weight, small volume, low cost and high performance, has received wide attention and rapid development in the field of military and civilian. Airborne data link transceiver system is an indispensable part of UAV system, and for the military UAV, the miniaturization of electronic products will improve the operational capability, so the miniaturization of airborne data link transceiver system has a very important significance. Based on the latest development of electronic chip technology and engineering practice, the specific design scheme of airborne data link transceiver system is given in this paper
