Abstract

In this paper we discuss the real time implementation and development of a front-end that is able to sample RF signals with a large bandwidth and dynamic range. This front-end uses an 8 channel RF multiplexer sampled by an 8 channel ADC board. A FPGA board is used to control the ADC and implements the digital synthesis filter bank. Preliminary results show that is possible to reconstruct the input signal.
