本文介绍了一种具有锐截止特性的毫米波低损耗鳍状线滤波器,它由数个凹槽组成.这些凹槽沿着单脊鳍状线周期分布.已测得 Q 波段(33—50GHz]的滤波器通带插入损耗为0.5—1dB.这一结果说明了鳍状线集成电路毫米波滤波技术上的先进性。
This paper presents a millimeter-wave low loss FIN filter with sharp-cut characteristics consisting of a number of grooves that are periodically distributed along a single ridgeline. The measured Q-band (33-50 GHz ] Filter pass-band insertion loss of 0.5-1dB.This result illustrates the finality of the millimeter wave filter IC technology.
