Abstract

In this paper, we will discuss the design, optimization, and measured results of the lumped-element bandpass filter (BPF) network used for submillimeter and millimeter imaging. Careful calculations are required during the filter design process to achieve a filter response that meets our needs. Circuit and layout models are studied to represent the filter transfer function with a physical layout. The measured results exhibit good frequency response and strong agreement with the predicted results. The proposed BPF network was used as part of the multicolor superconducting microresonator imaging array for the Caltech Submillimeter Observatory (CSO).
