Figure Lengend Snippet: Figure 3. Microwave dielectric properties and CTE of BaF2-(x wt %)LiF ceramics (A–C) The variation of (A) εr, (B) Qf, and (C) tf values with sintering temperatures and x values. The error bars indicate the difference in microwave dielectric properties between different test samples with the same composition. (D) CTE of BaF2-0.25 wt % LiF ceramics sintered at 700C. (E) Comparison of CTE values between the present ceramics and other LTCC substrates. The detailed data are listed in Table S2.

Article Snippet: To verify this hypothesis, two high-pass LTCC filters based on the dimensions of Mini-Circuits HFCG1760+ are constructed using BaF2-0.25 wt % LiF and Ferro A6M as the substrates, respectively (see Figure 4A).
