Abstract
A tunable YIG band pass filter which can be manufactured with reliably constant characteristics. A housing with slots for receiving insulating plates having a conducting layer on the side edge, and holes for receiving YIG elements over which indentations in the side edges having the conducting layers are located, provides the coupling loops of the filter to the YIG elements. The insulating plates and the YIG elements are fixed at predetermined positions.
