Abstract
A switch circuit includes: a first input and output terminal; a first inductor connected with the first input and output terminal; a capacitor connected with the first inductor; a second input and output terminal connected with the capacitor; a first MEMS switch connected with one end of the capacitor; a second MEMS switch connected with the other end of the capacitor; and a second inductor connected between the first MEMS switch and the second MEMS switch, and satisfies a relationship of f=1/(2π√CL)=1/(2π√CL), where Lis an inductance of the first inductor, Lis an inductance of the second inductor, C is a capacitance of the capacitor, and f is a use frequency.
