Abstract

The invention discloses a low-dielectric-loss microwave electronic ceramic material of which the expression is aZnO. bSiO2.cTiO2.dCaCO3.eAl2O3, wherein a, b, c, d and e respectively independently represent molar rates; and 35mol%<=a<=45mol%, 30mol%<=b<=35mol%, 0mol%<=c<=10mol%, 10mol%<=d<=20mol%, 0mol%<=e<=10mol%, and a+b+c+d+e=100mol%. The dielectric constant of the low-dielectric-loss microwave electronic ceramic material is 7-10; the low-dielectric-loss microwave electronic ceramic material has low loss (Qf is greater than 100000 GHz) and approximately zero temperature coefficient of resonance frequency; and by using the low-dielectric-loss microwave electronic ceramic, the dielectric resonator, filter and other microwave components can be more suitable for application in higher frequency and higher power, thereby being beneficial to improvement of the frequency and temperature stability of the device.

Description

technical field [0001] The invention belongs to the technical field of microwave dielectric ceramic material manufacturing, and in particular relates to a microwave electronic ceramic material with low dielectric loss. Background technique [0002] Microwave electronic ceramics is a new type of functional ceramic material developed in recent decades. It can be used as a dielectric material in microwave frequency band (mainly 300MHz ~ 30GHz) circuits and complete one or more functions. Key materials for microwave components such as oscillators, oscillators, and phase shifters. In recent years, with the rapid development of modern communication technologies such as mobile communication, satellite communication, global satellite positioning system (GPS), bluetooth technology and wireless local area network (WLAN), microwave technology has also shifted to higher frequencies, that is, to wider available frequency bands. Millimeter wave and submillimeter wave direction developmen...
