A radio frequency filter employing a dual notch structure, comprising:
- a C type notch structure formed in a predetermined region on a partition interposed between two cavities to be cross-coupled;
- and
- an L type notch structure formed along with the C type notch structure in the predetermined region of the partition between the two cavities,
- wherein the L type notch structure is formed in another region on the partition, separately from the C type notch structure, and includes a window that extends beyond a bottom of the C type notch structure towards a bottom of the partition.
