Abstract
We present the first frequency translator based on a nonlinear transmission line (NLTL) phase shifter. Rather than excite shock waves on the NLTL in large signal mode, we use its voltage-variable delay to modulate the phase of a 0.5-3.0 GHz microwave signal, incorporating both amplitude and phase linearization. This enables coherent heterodyning with 42 dBc carrier and spurious suppression. The technique has significant applications in both instrumentation and sensing.
