Abstract
A microwave power source comprises a Josephson junction or junction array and a resonant tank circuit coupled thereto and configured to resonate at one or more frequencies of Josephson oscillation. An output coupler is coupled to said resonant tank circuit for outputting microwave power from said resonant tank circuit. A bias circuit is coupled to the Josephson junction and configured to produce a bias voltage across the Josephson junction. Said bias circuit comprises a current path of variable resistance between a bias input of the microwave power source and a reference potential.
