Design of integrated submillimetric micromachined narrow band 5 pole filter at 150 GHz for earth observation

This paper presents new planar micromachined 5 pole bandpass filter topologies with narrow bandwidth and moderate insertion losses at 150 GHz. A 5 pole narrow band filter is presented at 150 GHz with 5 6 dB of insertion losses with a fractional bandwidth of 2% and high rejection (≫40 dB).
