Before building a digital receiver,a simulation using advanced design system can get the functions and performances to tutor the top designing.Then,the digital receiver consisting of 16 channels is built on a board(160 mm×233.35 mm).We demonstrate the 75 MHz anlalog signal is sampled by 120 MHz clock frequency.Subsequently,the DDC(digital down-converter) converters the central frequency to 0 Hz,and I/Q channels are set up.The instantaneous dynamic range of input is 75 dB.Compare with the results of the simulations,the performance of the digital receiver is eligible.
