Abstract
A transmitter (,) for communication devices according to the invention comprises a high-frequency power amplifier for amplifying the high-frequency signal to be transmitted, which high-frequency power amplifier includes an output stage for giving an amplified high-frequency signal, and measuring devices for measuring the power (P,) of the high-frequency signal. The measuring devices comprise devices (A,, RECT,, INT,, A,, RECT,, INT,) for measuring the voltage (V,) and current (I,) of the high-frequency signal in said output stage, and means (M,, INT,) for calculating the power of the high-frequency signal on the basis of the measured high-frequency voltage (V,) and high-frequency current (I,). A mobile station (,) according to the invention has a transmitter (,) for transmitting signals, which transmitter (,) includes a high-frequency power amplifier for amplifying the high-frequency signal to be transmitted. The high-frequency power amplifier includes an output stage (,) for giving an amplified high-frequency signal, and measuring devices for measuring the power (P,) of the high-frequency signal.
