Abstract

This paper mainly presents the frequency and temperature characteristics of a W-band attenuator, which include the correlation of signal frequency to attenuation and ambient temperature to attenuation respectively. Since the attenuation has dependence on input frequency and ambient temperature, the investigation on these characteristics is helpful to the application of the attenuator. With the adoption of the EncoderDrivetrade micro-positioner [1], the frequency and temperature characteristics of W-band attenuator may then be quickly explored despite the short system stability. The setup and the experimental results are discussed in details as well.
