The invention relates to a diplexer for connecting a transmitter and a receiver with one aerial, comprising a first block half (4) with a waveguide duct half (6) and a second complementary block half (5) with a waveguide duct half (6), which block halves (4, 5) jointly form a waveguide duct. The diplexer comprises a filter with a filtering portion, which comprises electrical discharge machined poles and has a foil form, the filter (15) being arranged between the block halves (4, 5) with its filtering portion between the waveguide duct halves (6) of the block halves (4, 5). <??>Further the invention concerns a method for manufacturing a diplexer, comprising the steps of forming a first block half (4) and a second complementary block half (5) and forming a waveguide duct half (6) in each block half (4, 5). The method further comprises the step of forming a filter with a filtering portion by making the filtering portion of a foil and electrical discharge machining poles in the foil. The method also concerns the step of assembling the filter and the block halves (4, 5) so that a waveguide duct with a filtering function is obtained, and placing the filter with its filtering portion between the waveguide duct halves (6) of the block halves (4, 5). <IMAGE> |
