Skyworks offers a broad range of ceramic materials that are not characterized for resonator applications, but for bulk, miscellaneous shapes, or substrates. Typical applications include patch antenna substrates, matching structures for circulators and isolators, and miscellaneous support structures. Because such applications are non-resonant, temperature coefficient of resonant frequency does not apply, and we therefore list the temperature dependent coefficients of dielectric constant and linear expansion.
The Magnesium Aluminum Titanate (SMAT) and Magnesium Calcium Titanate (MCT) series are notably easier to machine than most microwave ceramics, and may be more suitable for applications requiring precision machining.
D-4, or Corderite, is a very hard ceramic noted for its low temperature coefficient of expansion which approaches the metal alloy Invar. It is not suitable for substrates. It is occasionally used for dielectric resonator supports due to its low dielectric constant and/or low thermal expansion rate.
