摘　　要：针对微波设备小型化需求,利用低温共烧陶瓷(LTCC)技术,建立了小型化的LTCC电感和LTCC电容模型,并设计了内埋置LTCC电感和电容的片式L频段集总型带通滤波器,同时为了满足高频应用,设计了X频段分布带状线LTCC带通滤波器,通过用电磁场仿真软件ANSYS HFSS对滤波器进行建模及三维仿真优化,加工实现,制成的L和X频段LTCC带通滤波器的插入损耗分别<2.5 d B和<3 d B,体积分别为6 mm×3 mm×1.1 mm和3.1 mm×2 mm×1.1 mm,小型化效果明显。In this paper,the miniaturized Low-Temperature Cofired Ceramic （LTCC） inductor and capacitor model are established to meet the demand for miniaturization of microwave equipment.An L-band lumped band-pass chip filter with embedded LTCC inductor and capacitor is designed.An X-band strip line LTCC band-pass filter is also designed for high-frequency applications.The modeling and simulation of the filters are made by using electromagnetic simulation software ANSYS HFSS,and then test is performed after the filters are implemented.The results show that the insertion loss of the L-band LTCC band pass filter is not more than 2.5 dB and its size is 6 mm×3 mm×1.1 mm;while the insertion loss of the X-band LTCC band pass filter is not more than 3 dB and its size is 3.1 mm× 2 mm×1.1 mm only.
