Radio frequency micro-electro-mechanical switch and radio frequency device

A radio frequency micro-electro-mechanical switch, comprising:

• a substrate;
• and
• a signal electrode, a first ground electrode, a second ground electrode and a connecting membrane bridge,
• wherein the signal electrode, the first ground electrode, the second ground electrode and the connecting membrane bridge are disposed on the substrate, the connecting membrane bridge crosses over the signal electrode, and
• the connecting membrane bridge comprises a body portion and at least two stretchable structures,
• each of the stretchable structures is stretchable in a stretchable direction the same as an extending direction in which the connecting membrane bridge extends,
• an end of the body portion is connected to the first ground electrode through at least one stretchable structure of the at least two stretchable structures, and another end of the body portion is connected to the second ground electrode through at least one other stretchable structure of the at least two stretchable structures,
• the body portion comprises a base material of the connecting membrane bridge, and is provided therein with a plurality of opening patterns, the opening patterns each penetrate through the base material of the connecting membrane bridge.
