| Abstract: | This paper describes a novel and high precision three -channel transponder based on 3RR instrumentation system. The scheme of one channel coherent and two channels noncoherent is adopted by the transponder. The characteristics of IF modulation transponded scheme and IF mixed transponded scheme are compared, and some critical technology problemes such as special phase- locked loop, channel band- width, linear gain of great signal and small signal together are discussed in detail. |
