Attenuation Distribution Broadband Measurement System of Ceramic Pole Attenuator Used for TWT

Abstract:

Ceramic pole attenuator is an important part in TWT. The performance of TWT is closely related to the attenuation distribution of ceramic pole. The measurement of attenuation distribution was a difficult problem all the time. The traditional measurement method characterize the attenuation distribution by measuring the resistance distribution. The main disadvantage of this method is that result can not characterize ceramic pole’s performance in microwave condition. In this paper we select double-ridge waveguide as measurement transmission line, and based on the classical “Transmission and Reflection Method” an attenuation distribution measurement system was developed. This measurement system provides a convenient method to get accurate attenuation distribution in microwave condition. X-band and Ku-band ceramic pole attenuators were measured, and curves of attenuation distribution were given in this paper.
