    摘要: 可調式微波元件例如相移器,濾波器等等在微波工程上都有極高的應用潛能。傳統的順電材料薄膜,在微波的頻段都有超過0.01的損耗。為了減低微波損失,本文中將報導在鋇鈦氧化物酸的系統中摻雜鈦酸鍶形成一個低損耗的厚膜,在氧化鋁積基板上塗佈形成鈦酸鍶鋇的介電厚膜,利用鈦酸鍶鋇的可調能力,將厚膜製成可調式濾波器的原型。
    Microwave tunable devices, including phase shifter, filter, and others have great potential for applications in microwave circuits. Typical thin films of form paraelectric materials have loss tangent in the order of 0.01 or higher at microwave frequency. To suppress the microwave losses, thick films form dielectric materials were used. The thick films were screen printed on alumina substrate. A low loss, tunable thick film based on strontium titanium oxide (STO) combined with BaO-TiO(subscript 2) material system is presented. A prototype of tunable filter will be demonstrated.
