Surface-mountable metalized plastic waveguide filter suitable for high volume production

A millimeter-wave waveguide filter suitable for surface mounting has been designed and realized using plastic injection molding and metal coating technology. The manufacturing process enables low cost mass production of the plastic filters in high quality. In combination with fully automated SMD assembly techniques this concept allows the low cost integration of waveguide components into planar circuits, as it will be required in future mass market millimeter-wave transceiver applications, as for example LMDS or VSAT.
