Abstract
A micromachine switch for use in a millimeter wave circuit and a microwave circuit is simpler in structure than conventional micromachine switches. The micromachine switch has first and second high-frequency signal lines ( ), cantilever ( ) fixed to an end of the first high-frequency signal line ( ) and extending to a position above second high-frequency signal line ( ), first insulating means ( ) disposed on second high-frequency signal line ( ), second insulating means ( ) disposed in an area where cantilever ( ) and second high-frequency signal line ( ) confront each other, and first control signal line ( ) connected between an end of second high-frequency signal line ( ) and first insulating means ( ), for applying a control signal. When the control signal is applied to second high-frequency signal line ( ), cantilever ( ) is attracted to second high-frequency signal line ( ), and connected to second high-frequency signal line ( ) via second insulating means ( ) in a high-frequency fashion.
