Multilayered ceramic RF device |
摘要 |
A multilayered ceramic RF device having at least one radio frequency filter includes a low temperature-cofired multilayered ceramic body having a plurality of ceramic layers laminated one upon another and fired together. The low temperature-cofired multilayered ceramic body also has a first electrode pattern formed therein and a second electrode pattern formed thereon. The first and second electrode patterns are electrically connected to one another through a via hole. A bare semiconductor chip is mounted on the low temperature-cofired multilayered ceramic body with a face down bonding, and the bare semiconductor chip is coated with a sealing resin. The at least one radio frequency filter is a multilayered filter formed in the low temperature-cofired multilayered ceramic body, and the multilayered filter includes a part of the first and second electrode patterns.
