ABSTRACT:
A power amplifier integrated into an RF-IC (integrated circuit carrying radio frequency signals) comprises an active stage (350) and a passive stage (360), the passive stage being electrically coupled between the active stage and a load of the power amplifier. Electrically conductive elements (305) accomplishing an electrical connection between the active part and the passive part of an RF-IC are designed in a way that the electrically conductive elements perform at least part of impedance transformation on a signal path from signal output terminals of the active stage to signal output terminals of the passive stage.
