Abstract
Embodiments are directed to doubly balanced superconducting mixers and to methods for modulating a radio frequency signal using multiple tunable inductive elements in a doubly balanced superconducting mixer. In one scenario, a doubly balanced superconducting mixer is provided which includes an input port that receives an signal. The doubly balanced superconducting mixer further includes an IF control signal, a DC control signal and a filter that includes a first inner filter stage and a second inner filter stage. The first and second inner stages are coupled via a ring of tunable inductive elements, and are further inductively coupled to outer filter stages. The doubly balanced superconducting mixer further includes a controller that modulates the RF signal using the IF control signal and the DC control signal to tune the ring of tunable inductive elements to control transmission of the RF signal through the first and second inner filter stages.
