Development of an Integrated Millimeter-wave Fourier Transform Spectrometer

摘要

This paper presents the concept of an integrated millimeter-wave Fourier transform spectrometer. It is proposed to integrate the interferometer through the use of planar transmission line circuits onto a single chip. The splitting and combining of the broadband signal can be realized through the use of coupled-line couplers and the sliding reflector can be realized with distributed RF-MEMS transmission lines. Calculations are given to demonstrate the feasibility of this concept.
