摘要
研制了一种工作在W波段（75-110 GHz）的准光形式衰减器,该衰减器利用栅网的毫米波特性,并通过改善栅网的工艺,使得其在全W波段实现了可调衰减范围〉30 dB,插入损耗〈0.2 dB。该衰减器结构简单,成本较低,可重复性高,在毫米波测试中具有广泛的应用价值。
We have designed a quasi-optical adjustable attenuator which works on W-band（75-110 GHz）.Using the characteristic in millimeter wave of the wire grids whose fabrication has been advanced,this attenuator has achieved its dynamic range30 dB and insert loss0.2 dB.The attenuator has advantages of simplicity in structure,low cost and High repeatability.It has broad applications in the millimeter test.
