Abstract: A magnetron filter board for a microwave oven is disclosed. In embodiments, the magnetron filter board includes a printed circuit board with a first trace and a second trace on the printed circuit board. The first trace includes a first end for connecting to a magnetron and a second end for connecting to a power supply unit. The second trace also includes a first end for connecting to the magnetron and a second end for connecting to the power supply unit. The first trace and the second trace can be configured as a radio frequency band-gap filter that mitigates noise associated with the connection between the magnetron and the power supply unit.

Abstract: A door assembly for a microwave oven includes a door covering an opening of an oven housing. The door includes a bezel forming an outer frame to conceal internal door components and an inner door portion within the bezel made of a transparent material. An electromagnetic interference (EMI) attenuation device positioned around outer edges of the door includes folded transformer sections with dimensions based on an operative wavelength of electromagnetic energy generated by the oven. The EMI attenuation device attenuates EMI waves escaping the oven through a gap between the housing and the door. The transformer sections are positioned at an incline angle from a horizontal plane in which the transformer sections extend a greater distance in the horizontal plane than in a vertical plane to allow for a reduced bezel size and an increased area of the inner door portion.
