Abstract

RF receivers for airborne applications are critical systems for wireless signal reception and processing. Any unwanted interfering signals received by the receiver have a direct impact on the quality of the intended signals. The first paper, “Improved Complex Receiver System Design Strategies to Overcome EMI/EMC Challenges,” describes the strategies and implementation techniques for a complex receiver system design to meet environmental stress screening (ESS) requirements, especially EMC. The proposed design methodology segregates the various modules and stacks them together tactfully without compromising EMC. By applying these techniques, an actual design with four modules is demonstrated and tested for EMC compliance over an extreme temperature range from -40°C to +71°C.
