Abstract
Voltage controlled oscillator assembly which includes at least one voltage controlled oscillator, and a regulator for regulating the output power from the at least one voltage controlled oscillator.
Claims13
A voltage controlled oscillator assembly, comprising:
- at least one voltage controlled oscillator including an output stage and a micro-controller for digitally regulating output power from the at least one voltage controlled oscillator;
- and wherein
- the output power is controlled by applying a variable current bias to only the output stage and the output stage is within the at least one voltage controlled oscillator.
A method of regulating output power from at least one voltage controlled oscillator with a micro-controller comprising:
- providing information to the micro-controller specifying an output level of power to be provided by the at least one voltage controlled oscillator including an output stage;
- and
- generating a control signal from the information which is applied as a variable current bias only to the output stage of the voltage controlled oscillator to control the output power of the at least one voltage controlled oscillator to be in accordance with the information specifying the output power;
- and wherein
- the output stage is within the at least one voltage controlled oscillator.
