The H○02 mode transducer described in the paper consists of three parts: centre-excited type H10H○02 transdueer, H○02 mode taper and H10 mode taper. The design formulae of the relative parts are derived and the results obtained are given. The practical measurement at 8 mm band has been completed. It shows that the rejection to H○01 mode of the transducer is about 30 dB in 32-38GHz.
