Abstract
A bidirectional switch circuit is constituted of an FET group encompassing FETs of L stages (L≥3) connected in series to each other and includes an FET group configured to control electric conduction for a signal in both directions between one end and the other end of the above-mentioned FET group and a plurality of capacitance elements. The FET group includes a first FET closest to the one end and a second FET closest to the other end. The plurality of capacitance elements encompass a first capacitance element group including capacitance elements of M stages (1≤M<L) connected in parallel to each of the FETs from the first FET in sequence, and a second capacitance element group including capacitance elements of N stages (1≤N≤(L−M)) connected in parallel to each of the FETs from the second FET in sequence.
