ABSTRACT:
The antenna amplifier for mobile FM radio reception includes a signal amplifier, a controllable adjusting element having a PIN diode for impedance adaptation, and a control amplifier for regulating the adjusting element. The antenna amplifier has a compensation for the temperature response occurring as a result of very great differences (summer/winter) in ambient temperature, the PIN diode connection point is optimized, and the control range is maximized.
