Abstract
A millimeter wave transmission line filter having a plurality of filter pole determining coupled cavities fabricated with a multiple lithographic layer micromachining process. The filter cavities are oriented perpendicular to an underlying substrate element in order to achieve micromachining, fabrication and accuracy advantages. Multiple filters can be used in a frequency multiplex arrangement as in a duplexer. Radio frequencies in the 15 to 300 gigahertz range are contemplated.
