Abstract

Re₃Ga₅O₁₂ (Re: Nd, Sm, Eu, Dy, Yb, and Y) garnet ceramics were synthesized and their microwave dielectric properties were investigated for advanced substrate materials in microwave integrated circuits. The Re₃Ga₅O₁₂ ceramics sintered at 1350°-1500°C had a high-quality factor (Q × f) ranging from 40 000 to 192173 GHz and a low-dielectric constant (ε_r) of between 11.5 and 12.5. They also exhibited a relatively stable temperature coefficient of resonant frequency (τ_f) in the range of -33.7 to - 12.4 ppm/°C. In particular, the Sm₃Ga₅O₁₂ ceramics sintered at 1450°C exhibited good microwave dielectric properties of ε_r = 12.4, Q × f = 192173 GHz, and τ_f = -19.2 ppm/°C.
