Abstract
According to one aspect, an integrated circuit having a radio frequency amplifier includes at least two amplifier stages and an impedance matching device between two amplifier stages of the radio frequency amplifier. The matching device includes two lines which are coupled by electromagnetic induction. The first line is connected to an output of the first amplifier stage and the second line is connected to an input of the second amplifier stage.
