We demonstrate experimentally the operation of a double-balanced mixer, a phase shifter, and an I/Q modulator, built with Josephson junction active elements in a superconducting integrated ciruit. The devices operate at cryogenic temperatures with no power dissipation on chip, making them suitable for qubit control.
