We report the design of a sub-millimeter Fourier Transform Spectrometer of the Martin Puplett type (FTS-MP here after). The instrument will be installed on Sierra La Negra, and will operate from ~215 GHz to 1 THz approximately with a moderate resolution of 500 MHz. The main motivations of the work are the development of basic instrumentation for characterizing the LMT site (Large Millimeter Telescope) as well as optical components and to provide a portable broadband system for site testing. The collected data will be used for transmission model validation. The data also will influence the design of the new generation of sub-millimeter and millimeter cameras for the LMT. In the present work we emphasize cryogenic detector system design (bolometer detector and coupling optics) and the optical system layout for the FTS-MP. Test measurements in the laboratory are reported in this work.
