Abstract
This paper presents a method for designing temperature compensation for a resonant cavity using shape memory alloys (SMA). An SMA-driven tuning rod is proposed that will reduce temperature drift in a cavity resonator. A design method is proposed using closed form models derived from both microwave theory, and finite-element simulation. Tuning rod configurations using multiple SMA springs are proposed. A single-alloy spring design, and a two SMA spring design are tested. The single-alloy design reduces temperature drift of an aluminum resonator from 20ppro/°C to 10ppro/°C, while the two SMA design further reduces temperature drift to 9ppm/°C.
