ELECTRONIC DEVICE AND PACKAGE USED FOR THE SAME

摘要

[PROBLEMS] To provide a stacked ceramic electronic device applicable to two types of design specifications by using a common package. [MEANS FOR SOLVING PROBLEMS] In a stacked ceramic electronic device, filter chips (2, 3) for transmission and reception are mounted. A wiring pattern (7), which connects an input terminal (A) of a transmission filter chip (2) with a transmission side signal terminal (Tx) in a first arrangement embodiment, is provided with two branch wiring parts (72, 73) extending from the transmission side signal terminal (Tx) toward the input terminal (A) of the transmission filter chip (2) in the first arrangement embodiment and toward an output terminal (D) of a reception filter chip (3) in a second arrangement embodiment. A wiring pattern (8), which connects the output terminal (D) of the reception filter chip (3) with the reception side signal terminal (Rx) in the first arrangement embodiment, is provided with two branch wiring parts (82, 83) extending from the reception side signal terminal (Rx) toward the output terminal (D) of the reception filter chip (3) in the first arrangement embodiment and toward the input terminal (A) of the transmission filter chip (2) in the second arrangement embodiment.
