Abstract
The invention comprises a high-frequency low-pass filter ( ) The filter utilizes distributed capacitance and inductance elements ( ) which are realized using a homogeneous and relatively rigid conductive part ( ). The conductive part is located mainly air-insulated in an enclosed metal housing ( ) which serves as a ground conductor for the signal. The housing comprises conductive partition walls ( ) to prevent coupling between adjacent capacitive elements. The advantages of the construction include good power handling capacity, good breakdown characteristics, small losses and low manufacturing costs, among other things.
