FILER FOR REMOVING NOISE OF MAGNETRON AND METHOD THEREOF

摘要

PURPOSE: A filter for removing noise of magnetron and method thereof is provided to have characteristic of wide band by removing EMI noise occurring from band of over several hundreds MHz and by solving problem of temperature damage. CONSTITUTION: A shield box(100) is installed at input part of magnetron. A condenser(200) is installed at shield box(100). A seal type winding part(400) is formed so that many of turn part wound with the predetermined diameter is adhered closely each other. A complex type choke coil connects cathode terminal to terminal of the condenser installing small winding part(500) whose turning part wound with the predetermined diameter is formed in an interval of each other. A ferrite(600) of predetermined diameter is located in above seal type winding part.
