Considerations for designing wide-bandwidth multichannel systems
Next-generation aerospace and defence and test and measurement system bandwidths are moving from 10s to 100s of megahertz to multigigahertz of instantaneous bandwidths. Trends in phased-array radar, 5G wireless test systems, electronic warfare and digital oscilloscopes are pushing bandwidths higher and dramatically increasing the number of channels in a system.
These trends complicate signal-chain design, including the data converter, clocking and power supply. Selecting the appropriate data converter, synchronising multiple channels, and optimising your power supply are critical to achieving the necessary bandwidth across multiple channels.
