Claims
- 1. A complex electronic component, including:a first filter comprised of: a multilayer ceramic structure formed of a plurality of ceramic green sheet layers; at least one strip electrode; a capacitor electrode, the strip electrode and the capacitor electrode being formed on surfaces of the green sheet layers; and a second filter mounted inside a first cavity formed in a plurality of the layers of the first filter; further including a circuit device mounted on the first filter on a side thereof opposite the second filter.
- 2. The complex electronic component according to claim 1, wherein the first cavity is formed at the bottom of the first filter which forms a base for mounting the complex electronic component on a circuit board.
- 3. The complex electronic component according to claim 1, wherein said second filter comprises an SAW element.
- 4. The complex electronic component according to claim 1, wherein said strip electrode and capacitor electrode are cofired with said green sheet layers to form an integral unit.
- 5. The complex electronic component according to claim 1, wherein the circuit device is an active electronic element.
- 6. A complex electronic component, including:a first filter comprised of: a multilayer ceramic structure formed of a plurality of ceramic green sheet layers; at least one strip electrode; a capacitor electrode, the strip electrode and the capacitor electrode being formed on surfaces of the green sheet layers; a second filter mounted inside a first cavity formed in a plurality of the layers of the first filter; and a circuit device mounted in a second cavity formed in a plurality of the layers of the first filter; wherein the circuit device is an active electronic element.
- 7. The complex electronic component according to claim 6, wherein said second filter comprises an SAW element.
- 8. A complex electronic component, including:a first filter comprised of: a multilayer ceramic structure formed of a plurality of ceramic green sheet layers; at least one strip electrode; a capacitor electrode, the strip electrode and the capacitor electrode being formed on surfaces of the green sheet layers; and a second filter mounted inside a first cavity formed in a plurality of the layers of the first filter; wherein the first cavity is formed at the bottom of the first filter which forms a base for mounting the complex electronic component on a circuit board, and wherein a second cavity is formed at the top of the first filter.
- 9. The complex electronic component according to claim 8, wherein the portion of the first filter which forms the base includes external conductors for electrically coupling the complex electronic component to the circuit board.
- 10. The complex electronic component according to claim 8, further comprising a circuit device mounted in said second cavity.
- 11. The complex electronic component according to claim 10, wherein said circuit device is an active electronic element.
