摘要

A novel design methodology of a TE°21 /TE°01 mode converter for gyrotron traveling-wave tubes (gyro-TWTs) is presented in this article. This type of mode converter is characterized by its broad bandwidth. The proposed mode converter consists of two-mode conversion sections (TE°10 -TE°20 and TE°20 -TE°21 /TE°01 ) and an overmoded coupling section. The feeding TE°10 mode is first converted into the TE°20 mode, then coupled by using an overmoded coupling structure, and finally converted into the desired TE°21 /TE°01 mode. For verification, two H -band (220-325 GHz) back-to-back joined TE°21 /TE°01 mode converter prototypes were microfabricated and measured. The cold test showed that a measured 3-/2-dB transmission bandwidth of 58.9 GHz (235.2-294.1 GHz)/56.3 GHz (235.2-291.5 GHz) for the TE°21 /TE°01 mode converter was obtained.
