Transponder Downlink Ranging Channel Gain Control

In this paper, Transponder downlink ranging channel gain control analysis was presented. In normal case and worst case, characteristics of circuit was analyzed. Static regulation, dynamic regulation and loop rise time was calculated. Analysis result showed that the compression ratio(CR), Input modulation reduction(IMR) and loop rise time was 0.035%, 0.035%and 1.185msec(at normal case) 0.063%, 0.0649%, 2.14msec(at worst case) respectively
