Abstract:
1. A power amplifier for amplifying high frequency (HF) signals comprising: several amplifier elements (T_ a supply voltage (U_d) for the amplifier elements (T_ a selectable potential (U_g) that is present at the gate terminal (G) of the first amplifier element (T_ an HF input ( an HF output ( at least one capacitor (C_ at least one resistor (R_ characterized by at least one limiting path ( 7 ) that is connected between the drain terminal (D) and the gate terminal (G) of at least one amplifier element of the serial connection from the first amplifier element (T_ 1 ) to the next to the last amplifier element (T_ 3 ), whereby the limiting path ( 7 ) can be toggled between a conducting state and a blocking state corresponding to a voltage (U — ) that is present between the drain terminal (D) and the gate terminal (G) of the amplifier elements (T_ 1 , . . . , T_ 3 ).
