%X A 3 mm band IF switch radiometer was proposed.On the basis of discussing the theory as well as circuit structure and features,the performance of experimental prototype was presented.The research and experiment results show that not only its stability is better than that of total power radiomenter,but its cost and size are just similar to the latter because of absence of 3 mm band switch.It can surely meet the need of practical use.
