“…is generally lower than 950 °C. The ceramic dielectric resonators have significant advantages in miniaturization, lightweight, low loss, temperature stability and cost performance, taking an J u s t A c c e p t e d increasing share of the 5G filter market [4,5]. The key characteristics required for ceramic materials to fabricate dielectric resonators are high relative permittivity (𝜀𝜀 𝑟𝑟 ) for miniaturization, excellent temperature-stable dielectric properties (near-zero TCF value) and high Q × f value > 5,000 GHz for optimal frequency selectivity.…”

A series of high-k [(Na0.5Bi0.5)xBi1−x](WxV1−x)O4 solid solution ceramics with a scheelitelike structure are synthesized by a modified solid-state reaction method at a temperature range of 680-760 °C. The monoclinic (0 ≤ x < 0.09) to tetragonal scheelite (0.09 ≤ x ≤ 1.0) structural phase transition is confirmed by XRD, Raman and IR analyses. The effect of structural deformation and order-disorder caused by Na + /Bi 3+ /W 6+ complex substitution on microwave dielectric properties is investigated in detail. The compositional series possess a wide range of variable relative permittivities (24.8 ~ 80) and TCF values (-271.9 ~ 188.9 ppm/°C). The maximum permittivity of 80 and a high Q × f value of ~10,000 GHz are obtained near the phase boundary at x = 0.09. Furthermore, a temperature stable dielectric ceramic sintered at 680 °C with excellent microwave dielectric properties of 𝜺𝜺 𝒓𝒓 = 80.7, Q × f = 9,400 GHz (at 4.1 GHz) and TCF value = -3.8 ppm/°C is designed by mixing the x = 0.07 and x = 0.08 components. In summary, the similar sinterability and structural compatibility of scheelite-like solid solution systems make it potential for the LTCC applications.
