Abstract

The radio receiver comprises a controllable amplifier circuit (7) for amplifying radio signals. This amplifier circuit (7) includes an amplifier element (59, 67) with an input electrode (57) and a voltage divider coupled thereto. This voltage divider comprises an impedance (3, 65) and a control element (49). The amplifier circuit (7) can suitably be used to amplify signals having frequencies of approximately 200 kHz. The control element (49) comprises a PIN diode (49). This has the advantage that relatively little power is necessary to operate the control element (49).
