Abstract
An efficient method to accomplish thermal stabilisation of metallic coaxial cavities in terms of their resonance frequencies is presented. The mechanical structure required is simpler, lighter and cheaper than other solutions used. Several multi-cavity filters have been implemented using this technique. Measurements over a wide thermal range (150°C) show very good stability.
