Scientific paper

The design of a high spectral resolutionmillimeter wave heterodyne spectrometer assembly for spaceborne astronomy was studied. A frequency range of 300 to 500 GHz is planned with the possibility of extension to 1000 GHz. A microprocessor system with manual override controls the spectrometer. Subsystem studies are given for the diplexer, dichroics and optical input, mixer, IF system, local oscillator configuration, power conditioned, control loop configuration, and signal processor hardware. Required hardware developments are discussed.
