Two millimetre-wave filters (a Chebyshev 4-pole and a quasi-elliptical 6-pole 2 zeroes realized with dual-mode resonators) centred at 39 GHz are presented in this paper. They are both obtained by laser machining Alumina substrates and metallized with an electroless Copper plating technique. Laser etching is finally used again to etch the different patterns required for their input and output as well as other features. Despite the simplicity of this method, good agreements are obtained between… CONTINUE READING
