Title:
The amount element module of good changes
Document Type and Number:
Japanese Patent JP5978969
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a variable capacitance element module with a high ESD resistance property.SOLUTION: A substrate 30 is formed in a shape of a rectangular parallelepiped plate having a first side BS1 and a second side BS2 opposing each other with a variable capacitance element 14 interposed therebetween. A first substrate-side input/output terminal EP1 to connect a first input/output terminal P1 of the variable capacitance element 14 thereto and a second substrate-side input/output terminal EP2 to connect a second input/output terminal P2 of the variable capacitance element 14 thereto are disposed at positions along the first side BS1, and a substrate-side control voltage input terminal EVt to connect a control voltage input terminal Vt of the variable capacitance element 14 thereto and a substrate-side ground terminal EG to connect a ground terminal GND of the variable capacitance element 14 thereto are disposed at positions along the second side BS2. A first ESD protection element 17A is disposed between the first substrate-side input/output terminal EP1 and the substrate-side control voltage input terminal EVt, and a second ESD protection element 17B is disposed between the second substrate-side input/output terminal EP2 and the substrate-side ground terminal EG.
