ABSTRACT:
A mobile computing device and corresponding method are disclosed. The mobile computing device includes an RF MEMS switch circuit including at least one normally open RF MEMS switch and a normally closed RF MEMS switch and a controller connected to the RF MEMS switch circuit. The RF MEMS switch circuit applies a default condition to the mobile computing device through the normally closed RF MEMS switch, and the controller causes application of control signals to one of the at least one normally open RF MEMS switches and to the normally closed RF MEMS switch to apply an alternate condition to the mobile computing device instead of the default condition.
