Abstract:
A miniature double-throw electromagnetically actuated microwave switch comprising:a dielectric substrate having at least one input transmission line, a first output transmission line and a second output transmission line deposited on a front surface of said dielectric substrate for propagating and routing of microwave signals; a first cantilever connected to said first output transmission line and with a projection overlapping at least a part of said input transmission line; a second cantilever connected to said second output transmission line and with a projection overlapping at least a part of said input transmission line; a first permanent magnetic film deposited on a part of a top surface of said first cantilever for actuating said first cantilever; a second permanent magnetic film deposited on a part of a top surface of said second cantilever for actuating said second cantilever; an electromagnetic coil under said dielectric substrate for actuating said first cantilever and second cantilever.
