description There is provided a high-frequency HF transmitter for wireless microphones, guitar transmitters or pocket transmitters. The transmitter has at least one antenna (30, 70, 85), a power amplifier (40) for amplifying a high-frequency audio signal, an interference signal detection unit (60, 65) for detecting an interference signal coupled in by way of the antenna (30, 70, 85), a power detector (50) at the output of the detection unit (60, 65) for detecting the power of the interference signals detected by the interference signal detection unit (60, 65) and an operating point regulating unit (20) for adjusting the operating point power of the power amplifier (40) in dependence on the power of the output signals, that is detected by the power detector.
