摘要

本文介绍了一种低损耗、锐利带边滚降低通滤波器的设计和测量，该滤波器具有宽阻带和高抑制电平，截止频率为50 GHz，采用悬浮带状线(SSL)技术，实现在0.127 mm厚、介电常数为2.2的衬底上。所提出的结构由一个13阶广义切比雪夫低通滤波器组成，该滤波器在滤波器端口处具有集成波导到ssl的转换。该滤波器可用于毫米波下变频前端。利用三维全波模拟器对滤波器的最终设计进行了分析。测试结果验证了该滤波器的性能。

A Millimeter-wave High Selective Lowpass Filter in Suspended Stripline Technology

This paper represents design and measurements of a low loss, sharp band-edge roll-off lowpass filter with wide stopband and high rejection level with cut-off frequency at 50 GHz, using suspended stripline (SSL) technology, implemented on 0.127 mm-thick substrate with dielectric constant of 2.2. The proposed structure is comprised of a 13th order generalized Chebyshev lowpass filter which enjoys integrated waveguide-to-SSL transitions at filter ports. This filter can be used in frontend of a millimeter-wave down converter. Final design of filter is analyzed using 3D full-wave simulator. Measurement results are also presented to verify the performance of filter.
