Abstract:

This article describes how Ku band signal can be shifted to Ka band signal by frequency doubling.A large dynamic attenuation in Millimeter wave is designed.The output signal adopts accurate digital attenuation to control the large dynamic change,achieving fine concatenation match through two stages of waveguide isolator,and finally realizes ultra attenuation dynamic range to secure 90 dB attenuation in Ka Band.A prototype is produced and tested with good performance parameter,meeting the requirement of project specification.

Key words: Ka Band;frequency doubler;digital controlled attenuation
