Dual-mode band-pass filter |
摘要 |
A dual-mode band-pass filter having a greatly reduced size and a high design flexibility, includes a frame-shaped electrode pattern disposed on one surface or inside a dielectric substrate. A pair of input-output circuits are coupled to the frame-shaped electrode pattern. The plane shape and the line-width of the frame-shaped electrode pattern are configured so that two generated resonance modes are coupled to each other.
