Title:
MICROMACHINE SWITCH
Document Type and Number:
Japanese Patent JP2003217421
Kind Code:
A
Abstract:

To achieve low power consumption and high reliability by simplifying the arrangement of a switch mechanism and efficiently shutting a high frequency signal, in a micromachine switch for switching the high frequency signal.

This micromachine switch is provided with a signal line conductor 12 formed on a substrate, a driving short-circuiting mechanism 15 for shutting passing of the high frequency signal and a piezoelectric material 16 to be a driving means for displacing the driving short-circuiting mechanism 15 by imparting a control signal. By applying voltage as the control signal to the piezoelectric material 16, the signal line conductor 12 and a ground conductor 13 are short-circuited via a conductive layer 17 on a bottom surface of the driving short-circuiting mechanism 15 and the high frequency signal can be efficiently shut.
