Abstract
A high-frequency component which requires no shielding electrodes and in which there are no limitations upon the places where plural sets of filter components can be formed. In one embodiment, a high-frequency component has first to third ports, and includes a BPF connected between the first port and the second port and a BRF connected between the first port and the third port. The BPF and BRF comprise transmission lines and capacitors formed on a plurality of laminated dielectric layers. In another embodiment, the component comprises an HPF and an LPF formed on a plurality of dielectric layers. In both cases, the passbands of the respective filters are predetermined not to substantially overlap one another.
