A wide band tunable microwave oscillator for monolithic microwave integrated circuits. The oscillator does not use varactors or inductors for oscillation, but uses a voltage variable resistor coupled to a first MESFET supplying a capacitance, and to an amplifying element to create an RC oscillator. The voltage variable resistor is a second MESFET coupled to a variable voltage source. The oscillator takes advantage of the gate capacitance of the first MESFET, as well as the gain available from using an active element within the feedback loop.
