Abstract :
Novel structure of mixer based on circular groove guide (CGG) was proposed. A planar logarithmically periodic antenna was installed in the guide. It received signals in the guide and transmitted them to the mixer diode. A compact multi-section coaxial filter was arranged to lead the intermediate frequency signal out of the shell. Experiments were done at 12.435GHz and 33.069GHz respectively. The successful experiments proved the feasibility of CGG mixer and the broadband property of CGG.
