Multichannel RF transceiver reference design for radar and electronic warfare applications

This reference design, an 8-channel analog front end (AFE), is demonstrated using two AFE7444 4-channel RF transceivers and a LMK04828-LMX2594 based clocking subsystem which can enable designs to scale to 16 or more channels. Each AFE channel consists of a 14-bit, 9-GSPS DAC and a 3-GSPS ADC that is synchronized to less than 10ps skew with > 75-dB dynamic range at 2.6 GHz.
