AD9361  AGC

A problem occured when I use AD9361 in a UAV datalink project. The grond command control station received sigals with huge strength fluctuation during the process of flying.The link monitoring software showed  the AGC value up and down along with  link interruptions.But the signal strength was always strong enough for the receiver to sync and decode,about 30dbm above the demodulation threadhold.Sometimes I can detect phase inversion when the receiver's AGC value of AD9361 jumps.I figure that the sudden change of the AGC value cause the problem.Any idea to fix it?Thanks in advance!

 

Best regards!
