Abstract

The substrate-integrated waveguide balance filter for wavelet / millimeter wave circuit comprises: a metal paster (1) on the media substrate (2), which has rectangular middle and Y-shaped ends; a row of first / second metal through holes (31) / (32) on side of paster midst edge; three rows of paralleled third / fourth / fifth metal through holes (33) / (34) / (35) between (31) and (32) on the paster middle line, and four couple of through holes on sides of the paster middle line arranged from the input end (4) to the first isolation end (5).

Description

technical field [0001] The invention is a substrate-integrated waveguide balanced filter that can be applied to the design of microwave and millimeter wave circuits and can also be used in the design of microwave and millimeter wave integrated circuits, belonging to the technical field of microwave filters. Background technique [0002] Microwave and millimeter wave filters are at the center of many design issues in microwave and millimeter wave RF systems such as frequency converters, frequency multipliers, and multiplex communications. The electromagnetic spectrum is limited and must be allocated according to the application; the filter can be used to radiate in the specified frequency band with an unrestricted high-power transmitter, and in turn can be used to prevent the receiver from being interfered with outside the operating frequency band. In addition to selecting the frequency to pass through, the balanced filter can prevent the signal at the stop band frequency fro...
