摘要
Abstract
Firstly a variety of layout structure of LTCC(Low Temperature Co-fired Ceramic) filter are introduced in this paper, then the advantage and disadvantage are analyzed in brief. Finally the process difficulties and the corresponding solution were presented which has been occurred during the manufacturing process. Emphasis is placed on the design of 600MHz low pass filter with compact size. The LTCC material is a dielectric constant εr of 7.8 and a loss tangent of 0.006, the outline dimension of the filter is 5.1mm ×3.3mm×1.6mm. Furthermore, the filter is designed by the method of combine electromagnetism with circuit. The product sample was tested by using vector network analyzer, the results show that the maximum insertion loss in passband is 1.8 dB and match very well with the design reqirement. The filter has small size and excellent frequency property. It can be widely employed in compact microwave communication systems and radar systems.关键词
