摘要
静磁前向体波(MSFVW)要求外加直流偏置磁场和静磁波波导YIG膜平面相垂,因而极易安排直流磁路和微波电路。把一个MSFVW阵列置于一个线性渐变外磁场中,每个滤波器中心频率不同,形成一个信道接收器,可完成不同频率信号的实时分离。本文从理论和实验说明这种器件的特性,并指出器件实用化尚需进行的工作。
The direction of DC magnetic field is perpendicular with YIG film in MSFVW devices. So it is easy to arrange for magnetic and microwave circuits. A MSFVW filter array biased by a linear gradient DC magnetic field is a channelizer. This type filter bank could be used as multiplexer and demultiplexer on-time. A prototype is described. Of course, MSFVW channelizer is in an advanced stage of deve lopment.
