Abstract
An integrated power amplifier arrangement with multistage construction is provided, in which a matching filter with integrated capacitance and inductance for impedance transformation is provided between an input transistor and an output transistor. In one example, the inductance of the matching filter is formed as a microstrip conductor, resulting in a significantly higher quality factor of the inductance and hence an improved linearity and an improved efficiency of the integrated power amplifier. The invention can advantageously be employed in particular in integrated transmitting arrangements.
