Abstract
According to a wireless circuit, in a case where a control section carries out switching between use frequency bands of an antenna, the control section sets, in accordance with a first set value which has been adjusted by an impedance variable matching section before the switching, a set value of an impedance variable matching section after the switching. This prevents communication, which is carried out by the wireless circuit including the variable matching section, from being cut off when the use frequency band are switched.
