Abstract

The paper presents a 5th order bandpass filter for communication satellite feed systems, fabricated using 3D-printing with Titanium alloy Ti-6Al-4V or Ti64. Taking advantage of the alloy's high strength-to-weight ratio, the filter is printed with a wall thickness of only 1 mm and a weight of 40 g. Ti64 also has a much lower coefficient of thermal expansion than aluminium. The filter was designed with modified rectangular cavity resonators with rounded corners, enabling monolithic printing of the structure in a lying-down position without any internal supports. The coupling irises have been moved to one side of the filter to facilitate polishing and silver coating. The measured response of the as-printed filter showed a minimum insertion loss of 2.7 dB and a frequency shift of about 140 MHz. After silver plating, the insertion loss was significantly reduced to a minimum of 0.55 dB. The challenge with plating on the Ti64 filter has been discussed.
