Micromachined microwave cavity filters offer a light-weight, high-Q and highly integrated alternative in the frequency range of 20 GHz ?? 100 GHz as compared to conventional filter types. This paper explores a structured design approach that uses mode matching synthesis to relate this (distributed) filter technology to a lumped element prototype circuit and refine the filter response. This filter technology shows much potential for use in 5G portable devices and as such, the design of a set of duplexer bandpass filters is demonstrated for this targeted application area.
