The phase comparator connects the transmission circuitry to the receiving circuitry via a shunt switch to compare the intended phase with the actual phase. The phase of a signal received via the shunt switch is sensitive to the performance of power amplifiers in the transmission circuitry, transmitter/receiver switch, and load impedance. Distributed attenuators between the shunt switch and a phase comparator reduce crosstalk. Phase comparison circuitry is useful for detecting faults in the ESA radiating element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio frequency power output control and detection for electronically scanned array system","description":"Electronically scanned array antenna radiating elements include a phase comparator.
