Miniaturized and out-of-band improved bandpass filter in Si-BCB technology

This paper reports on the design of a 24 GHz bandpass filter. This device is developed in a multilayer BCB-Si technology to ensure the development of the system on a unique chip. Moreover the technique of integration of semi-lumped lowpass filters in bandpass filter is used to reduce the global size and eliminate spurious response of the filter. The general method to design this kind of filters is described and experimental results are presented.
