Designing rugged, multifunctional HPA controllers to prevent system damage
High Power Amplifiers (HPAs) are critical in microwave systems commonly found in Electronic Countermeasures (ECM), Electronic Warfare (EW) simulators, radar, and communications links used by the military. Unfortunately, integral Vacuum Electron Device (VED) requirements introduce hostile environments for HPAs. However, a rugged, multifunctional, microcontroller FPGA-based controller can solve this challenge.
