Transmitter for communication devices

A transmitter for communication devices, comprising:

• a high-frequency power amplifier comprising an amplifying component having an input port for receiving a high-frequency signal to be transmitted and an output port for outputting an amplified high-frequency signal to be transmitted,
• first measurement means, being at least partly coupled between said input port and said output port of said amplifying component, for generating a first indication describing the voltage of said amplified high-frequency signal in said high-frequency power amplifier,
• second measurement means, being at least partly coupled between said input port and said output port of said amplifying component, for generating a second indication describing the current of said amplified high-frequency signal in said high-frequency power amplifier, and
• calculating means for calculating the power of the amplified high-frequency signal in said high-frequency power amplifier based on said first indication and said second indication from between said input port and said output port of said amplifying component.

A mobile station, which includes a transmitter for transmitting signals, which transmitter comprises:

• a high-frequency amplifier for amplifying the high-frequency signal to be transmitted, which high-frequency amplifier includes an amplifying component for producing an amplified high-frequency signal, and
• measuring devices for determining the power of the amplified high-frequency signal, wherein the measuring devices comprise:
• first means for measuring the voltage and the current of the amplified high-frequency signal in the high-frequency power amplifier, said first means being at least partly coupled to two sides of said amplifier component to separately measure said voltage and current, and
• second means for calculating the power of the amplified high-frequency signal based on the separately measured voltage and current of the amplified high-frequency signal.
