Highly Integrated Submillimeter-Wave Spectrometer for CubeSats

We are developing a highly integrated submillimeter-wave spectrometer suitable for CubeSat and SmallSat platforms. Since the available space and DC power on a CubeSats is limited and the instrument has to be light weight, traditional methods of assembling submillimeter-wave instruments are not suitable on these platforms. In this paper we show how we are addressing all these by using low-profile antennas, MEMS calibration switch, and CMOS spectrometers.
