摘要： Voltage controlled oscillator assembly, comprising at least one voltage controlled oscillator, and means for regulating the output power from the at least one voltage controlled oscillator. Preferably said means for regulating the output power is a micro-controller (16) arranged on the same chip as the voltage controlled oscillator (3). The voltage controlled oscillator assembly is typically incorporated in a phase locked loop and used in different mobile telephone constructions. The present invention ensures that the output signal of the voltage controlled oscillator has a level which is sufficient but not too powerful and which is adjusted to the actual application. Reduced losses are achieved.
