Piezoelectric oscillator, voltage-controlled oscillator, and production method thereof |
摘要 |
The invention provides a piezoelectric oscillator including a semiconductor integrated circuit and a piezoelectric resonator, and also a voltage-controlled oscillator including a semiconductor integrated circuit, a piezoelectric resonator, and another electronic component, characterized in that the piezoelectric resonator having a case with cross-section of an elliptic or a track-like (combination of a rectangle and two semicircles) shape, the semiconductor integrated circuit, and the electronic component are molded with a resin into a very thin unit in the form of a surface mounting structure. <IMAGE> |
