Abstract

High-quality (1 - y)(Mg_0.95Co_0.05)₂(Ti_0.95Sn_0.05)O₄-y( Ca_0.61Nd_0.8/3)TiO₃ ceramics were prepared by solid-state reaction. The products were characterized by scanning electron microscopy, X-ray diffraction, and network analyzer. (Mg_0.95Co_0.05)₂(Ti_0.95-Sn_0.05)O₄ (MCTS) has a dielectric constant (ϵr) of ~14.7, a high quality factor (Q×f ) of ~330, 134 GHz, and a temperature coefficient of resonant frequency (τ_f) of ~ -46 ppm/°C. 0.48 MCTS -0.52CNT has an excellent combination of microwave dielectric properties: ϵr ~ 28.58, Q×f ~ 208027GHz (at 9 GHz), and τ_f ~ -4.38ppm/°C sinter at 1325°C, and can be utilized in the fabrication of microwave devices. Therefore, a band-pass filter is designed and simulated using the proposed dielectric to study its performance.
