• In this paper we present a method for designing temperature compensated cavity resonators using shape memory alloys (SMAs). This paper gives a formula for the temperature drift of resonant frequency, which is valid for any conductor-loaded cavity regardless of its shape. This formula is combined with a field perturbation model and used to derive mechanical design constraints from a temperature drift constraint. Experimental results are given that confirm the feasibility of the proposed design approach.
