Patent ID: 8098108

Claim:
A microwave oscillator using integrated circuit technology, the oscillator comprising: a variable capacitance element for changing a frequency of the oscillator as a function of a control signal Vt applied to the variable capacitance element; a microwave output providing an oscillation frequency as a function of the control signal Vt; the oscillator further comprising a first control input driven by a first control signal Vt 1 to control a central frequency Fc of the oscillator; and a second control input driven by a second control signal Vt 2 to control a linear modulation of the central frequency Fc, wherein: the control signal Vt of the oscillator is derived from a predetermined function of the first control signal Vt 1 and the second control signal Vt 2 in accordance with the following relationship: Vt=Vt 1 −F ( Vt 2) wherein the function F generates the voltage F ( Vt 2) =k ( Vt 2) ×Vt 2 from the second control signal Vt 2 , wherein k is a function of the second control signal Vt 2 , expressed by k(Vt 2 ) and comprises a parameter between 0 and 1.
