Abstract

This paper provides examples of the use of direct print additive manufacturing to fabricate RF/microwave and optical components. Direct print additive manufacturing is the combination of extrusion and micro-dispensing on a single tool. The design, 3D printing process and material selections for finite ground coplanar waveguide (FG-CPW) planar transmission lines, the integration of DC contact RF MEMS switches within the FG-CPWs, and optical interconnects are detailed. Picosecondpulsed laser machining is performed to enhance the finish quality of the devices and achieve minimum feature size down to 6 μm specifically for the RF switch.
