METHOD AND CIRCUIT ARRANGEMENT FOR CONTROLLING THE OUTPUT POWER OF A POWER AMPLIFIER
According to the invention, the regulation of output power of a power amplifier (1), in particular, a high frequency power amplifier, is achieved, whereby a control parameter (STELL) for the power amplifier (1) is generated, by means of a closed loop (2) and the amplification of the closed loop (2)...

| Zusammenfassung: | According to the invention, the regulation of output power of a power amplifier (1), in particular, a high frequency power amplifier, is achieved, whereby a control parameter (STELL) for the power amplifier (1) is generated, by means of a closed loop (2) and the amplification of the closed loop (2) is adjusted depending upon the value of the control parameter (STELL). A so-called rollover' of the power amplifier can thus be avoided, whereby the amplification of the closed loop (2) can be reduced when the control parameters (STELL) occur, which would lead to an output power close to maximum power of the power amplifier (1) occur. |
