Power amplifier arrangement, particularly for mobile radio, and method for determining a performance parameter |
摘要 |
A power amplifier arrangement includes a power amplifier with an input for a radio-frequency signal and an output for delivering a second radio-frequency signal. The second radio-frequency signal has a current and a voltage. A second element is configured to deliver a first signal derived from the current of the second radio-frequency signal. Furthermore, a first element is provided to deliver a second signal derived from the voltage of the second radio-frequency signal. An evaluating circuit detects in-phase components of the first and the second signal. As a result, in-phase current and voltage components can be detected together which produce the active power of the second radio-frequency signal by multiplication.
