| 摘要 |
The invention relates to a method and a circuit arrangement for preventing the oscillation of a radio frequency power module (IC1). According to the method of the invention a coupling element (Q7), preferably a bipolar transistor, which is made conductive when the input signal (IN) is removed, is installed between the input (IN) and the ground. The supply voltage (VS) in the power module can be permanently switched on.
