Device to control the output power of a class C amplifier |
摘要 |
Disclosed is a device to control the output power of an amplifier working in class C mode and comprising at least one bipolar transistor. The bias resistance of the bipolar transistor is made variable through the presence of a field effect transistor, to the gate of which is applied a voltage Vgs, chosen from a set of values that are determined experimentally as a function of the output power to be obtained, the power and frequency of the input signal and the temperature of the bipolar transistor.
