Ba(Zn1/3Nb2/3)O3為一微波介電陶瓷材料其介電特性εr約41,Q ×f 約為54000,τf則約為30 ppm/℃;本論文試以添加不同比例的BaZrO3混合成Ba[ZrxZn(1-x)/3Nb2(1-x)/3]O3,其中x值從0.02、0.04、0.05、0.06到0.08,結果顯示當x = 0.05時其微波介電特性最佳:εr = 41.28,Q ×f = 96000。
另外,本論文還使用了三種材料:玻璃纖維(FR4)、Al2O3、0.95Ba(Zn1/3Nb2/3)O3-0.05BaZrO3作為基板,以交錯耦合方式來實現準橢圓濾波器;濾波器規格為:中心頻率5.2 GHz,頻寬10%,利用軟體模擬並與實作結果作一比較。
Ba(Zn1/3Nb2/3)O3 ceramics is a microwave dielectric material. Ba(Zn1/3Nb2/3)O3 ceramics has a dielectric constantεr = 41,a quality factor Q ×f = 54000,and a temperature coefficient τf = 30 ppm/℃;In this thesis , Ba(Zn1/3Nb2/3)O3 ceramics had been became Ba[ZrxZn(1-x)/3Nb2(1-x)/3]O3 , x = 0.02、0.04、0.05、0.06、and 0.08 , by adding BaZrO3 . And finally the best properties of the microwave dielectric are εr = 41.28,Q ×f = 96000,when x value equal 0.05 .
In addition , the materials , FR4、Al2O3、0.95Ba(Zn1/3Nb2/3)O3-0.05BaZrO3 ,had accomplished the dielectric substrates in this thesis. And qusi-elliptic filter had been realized by using cross-coupled structure . The standard of the filter is 5.2 GHz and the bandwidth of the filter is 10 % .
And we compared the result of the simulation with the result of the measurement of the performance .
