Dual-mode band-pass filter

   
   

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.

Un filtro band-pass del dual-modo que tiene un tamaño grandemente reducido y una alta flexibilidad del diseño, incluye un patrón marco-formado del electrodo dispuesto en un superficie o interior un substrato dieléctrico. Un par de circuitos de la entrada-salida se junta al patrón marco-formado del electrodo. La forma plana y el line-width del patrón marco-formado del electrodo se configuran para juntar dos modos generados de la resonancia el uno al otro.
