Microwave filter with tunable cutoff frequency and its application to the microwave mixer and to the radar operating in diversity mode

摘要

The invention relates to microwave filters produced from waveguide segments. The object of the invention is to modify the cutoff frequency of a waveguide 40, 41 by moving a dielectric blade 43, 44 inside this guide. The invention applies in particular to the production of microwave mixers and to their application in radars operating in diversity mode. <IMAGE>
