A multi-layered printed circuit board embedded with a filter, the
multi-layered printed circuit board using a composite multi-layered
printed circuit board formed of at least a high dielectric material
stacked with at least a low dielectric material. A plurality of serial or
parallel capacitors are disposed in the composite multi-layered printed
circuit board so as to form a filter. At least one capacitor is an
interdigital capacitor disposed on a low dielectric material. Metal
electrodes of the interdigital capacitor are located on the same plane
such that the area of the metal electrodes or the spacing between the
metal electrodes can be adjusted in advance to precisely control the
electrical properties such as the center frequency and the transmission
loss of the filter. Problems resulting from alignment errors caused in
manufacturing the composite multi-layered printed circuit board can also
be prevented.
