[(Mg1–xZnx)0.95Co0.05]1.02TiO3.02 ceramics were fabricated using solid-state synthesis for mobile communications. Zn2+ and Co2+ substitution enhanced the Qxf value and allowed densification sintering at lower temperature compared to that for [(Mg1–xZnx)0.95Co0.05]1.02TiO3.02, which must be sintered at 1175°C. [(Mg0.6Zn0.4)0.95Co0.05]1.02TiO3.02 sintered at 1175°C has a dielectric constant of 20.1, a Qxf value of 280,000 GHz, and a τf value of –64.7 ppm/°C. The maximum quality factor multiples resonant frequency (Qxf) value of around 280,000 GHz was obtained for the [(Mg0.6Zn0.4)0.95Co0.05]2TiO4.
