[[Image:MISTRAM-transponder.jpg|thumb|MISTRAM "A" Model Transponder]]
The Transponder receives the two phase-coherent X-band cw signals transmitted from the ground equipment. A klystron with a 68&nbsp;MHz coherent frequency offset is phase locked to each of the received signals. These klystrons provide the phase coherent return transmission. There are two separate [[phase locked loop]]s, continuous and calibrate.
