    • The invention relates to an adjusting circuit for adjusting an amplitude of a radio frequency signal. The adjusting circuit comprises a plurality of terminals for input and output, a matching component having an effect on matching a signal input and a signal output to and from the terminals. The adjusting circuit also includes at least one adjustable resistance unit between the matching component and ground for changing a resistance of the input and the output of at least one terminal of the amplitude adjusting circuit. The adjusting circuit for adjusting an amplitude of a signal also may include a plurality of terminals for input and output, at least one pair of adjustable impedance units. Each pair of the adjustable impedance units is placed between a pair of input and output terminals. Each of the adjustable impedance units is coupled in parallel between a signal line and ground, and the impedance units of each pair have complementary reactances with respect to each other.
