Polarized wave separator

・Polarized wave separator Polarization wave separator is classfied into two types:circular polarization wave
separator and linear polarization wave separator.

As the unit is composed entirely of metallic components, it can be used in ultra-low temperature environments (down to ～1K).

We manufacture products for a wide range of frequencies, and we also offer custom designs based on your specific requirements.

For any questions or inquiries about the product, please contact us via the inquiry form or phone at 0422-52-0167.Custom orders are also available, so please feel free to consult with us.

System

Circular Polarizer
円形導波管がport1、それが分岐してport2とport3がある。port1に円偏波を入力すると偏波の回転方向によってport2かport3から出力される。可逆である。詳しくは表を参照。
input port input polarized wave output port output polarized wave
Port1 right rotation circularity
polarized wave(CW)		 → port2 linearly polarized wave
Port1 left rotation circularity
polarized wave(CCW)		 → port3 linearly polarized wave
Port1 linearly polarized wave → port2 & port3 linearly polarized wave
Port2 linearly polarized wave → port1 right rotation circularity
polarized wave(CW)
Port3 linearly polarized wave → port1 left rotation circularity
polarized wave(CCW)
