Insertion Loss Handling Procedures The following precautions should be observed to avoid damage: Static sensitivity -- RF MEMS switches integrated circuits are ESD sensitive and can be damaged by static electricity. Use proper ESD precautions when handling these devices. Maximum Rating -- The absolute maximum input power is 2 watts.
