ADI has expanded its True Time delay offerings with the ADAR4000 and ADAR4001. These are highly integrated products, providing multiple channels operating from 2-18 GHz. The true time delay cores ensure beam-squint free wideband operations. Both devices have four channels, each with a 7-bit true time delay (TDU) and a digital step attenuator (DSA). The total time delay range is 508ps per channel and includes programable amplifiers and on-chip memory, all in a 6mm x 6mm package.   ADAR4001 Datasheet and Product Info | Analog Devices
