28 nm Analog-to-Digital Converters Enable Next-Generation Electronic Warfare Receiver Systems

The ever-present need for higher bandwidth and lower size, weight, and power (SWaP) in electronic warfare (EW) receivers, specifically those for signal intelligence (SIGINT) applications, has EW system designers continually looking for new developments and improvements in high speed analog-to-digital converter (ADC) technology. While 65 nm ADCs approach their inherent, process-related performance and bandwidth limitations, new 28 nm RF ADCs surpass these boundaries and form a new foundation for next-generation wideband receiver systems. A 28 nm process node’s smaller transistor widths and lower parasitics enable faster sample rates, wider analog input bandwidth, integrated digital functionality, and new receiver architectures, all while reducing power consumption and overall size.
