Abstract
For analysing the sub-millimeter radiation received by a astronomy satellite, a hybrid analog-digital spectrometer is planned. As a critical part of this instrument, a specific digital signal processing chip set is proposed. A first strategy is based on a GaAs MESFET chip expected to perform 52 giga-operations per second with a 400 MHz clock frequency. While this strategy gave encouraging results and remains the main line of the project, a second strategy based on parallelism on silicon only is under study, and the opportunity of working simultaneously on two opposite approaches is discussed.
