Abstract
A high frequency power detector includes an input coupling arrangement that couples an electrical HF-oscillation into a basic circuit portion including at least a first diode and a circuit node. The power detector further includes a series circuit of a resistor and a second diode connected to the circuit node, as well as a voltage tapping arrangement for detecting or tapping the voltage drop across the second diode as an output signal. The voltage at the circuit node includes a DC component that depends on the power of the HF-oscillation. The output signal, i.e. the voltage drop of the second diode, has a linear voltage characteristic relative to the HF-power in dBm. A method of regulating the HF-power uses such a dBm-linear HF-power detector in a feedback loop for regulating the gain factor of an HF-amplifier.
