C-band Pulsed Magnetron from China
A pulsed magnetron operating in the C-band frequency range (4-8 GHz), used primarily in radar transmitters for air traffic control and meteorological applications. It falls under HTS 8540.71.40.00 as a microwave tube classified as 'other' magnetron, excluding grid-controlled types, designed for high-power pulsed operation.

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
