Abstract: This paper introduces the design for redundant switch of frequency shift transmitter, studies the frequency shift failure problems of transmitter in practical application, mainly including instable redundant switching problems caused by soft fault of transmitter and the inability of the transmitter to self-check its own internal circuit break, therefore to explore feasible solutions from the perspective of transmitter design.

Key words: frequency shift transmitter, redundant switching design, practical application
