Abstract
A two-inductor varactor tunable solid-state microwave oscillator comprising a series tunable circuit wherein one inductor is serially connected with a negative resistance active element, an impedance load, and a varactor. The circuit is tuned by changing the reactance of the circuit by varying electrically the capacitance of the varactor. The second inductor is connected in parallel with the varactor to increase the range of reactance change of the series circuit effected by the variation in capacitance of the varactor to provide thereby for a wider frequency tuning range.
