Abstract

In this paper we present a switched-capacitor matched filter for the satellite on-board data handling (OBDH) Litton coded bus. The proposed filter represents the analog front-end of the bus interface (modem) in the central data management unit (CDMU) and in each remote terminal unit (RTU) of the satellite on-board communication system. The filter consists of a 16-taps switched-capacitor FIR structure, implemented using a mixed serial/parallel architecture which allows optimal performance to be achieved with a minimum number of components. Simulation results confirm the validity of the proposed approach. The complete modem is being integrated in a 0.8 μm BiCMOS, SOI, rad-hard technology
