reflection filter

The adjustment of reflectance of side bands and wide of main band for reflection type resonance filter

反射式共振滤光片的旁带反射率和滤波带宽的计算

In order to increase the bandwidth of tunable fiber laser, a large channel spacing and bandwidth multi-channel filter with same reflection peak is required.

为了增加可调谐光纤激光器的调谐带宽，需要一种具有大信道间隔、大的总带宽、各信道的峰值反射率在带内保持均匀而在带外迅速下降的多信道滤波器。

In order to filter out reflection by using time-gate of the network analyzer, the modified design of the reasonable height of device and the form of the impedance transition are discussed in this paper.

文中主要讨论如何设计同轴反射计的合理高度及阻抗过渡形式，并利用网络分析仪的时域门将装置阻抗失配所引起的反射滤除，使测试结果更为准确。
