Nonreciprocal microwave devices using parametric frequency conversion

This thesis endeavors to characterize the performance of nonreciprocal microwave devices enabled by parametric frequency conversion. Although such devices have been explored somewhat superficially in the 1960s, resurgent interest in low-noise nonreciprocal components has motivated new research in parametric frequency conversion. In particular, this work explores the contributions of nonidealities to performance degradation of a parametric gyrator. Expressions are developed for loss and noise performance contributed by nonideal components constituting the gyrator, and simulations are used to verify the findings. The gyrator is then used to construct a circulator, and its performance's dependence on the same nonidealities is evaluated. A simulated design example is used to demonstrate a practical realization of such a circulator.
