  • Surface-mounting type electronic circuit unit suitable for miniaturization
    Patent number: 6518658
    Abstract: To provide a surface-mounting type electronic circuit unit suitable for miniaturization, circuit elements including capacitors, resistors and inductance elements and a conductive pattern connected to these circuit elements are thinly formed on an alumina substrate, semiconductor bare chips for a diode and a transistor are bonded on a connection land of the conductive pattern via wire, an inductance element composed of a pair of conductors opposite at a predetermined interval on the aluminum board is thinly formed and a unbalance/balance converter is formed by these conductors.
    Type: Grant
    Filed: May 29, 2001
    Date of Patent: February 11, 2003
    Assignee: Alps Electric Co., Ltd.
