Import Tips
• Verify frequency specifications and power output in technical datasheets to confirm classification as a non-grid-controlled magnetron
• Include FCC compliance documentation if intended for radar use in the US to avoid regulatory delays
• Beware of misclassification as klystrons (8540.71.50); magnetrons have crossed-field electron flow
