什麼是切換器? What is RF Switch

什麼是切換器(RF Switch)

 

 

 

RF Switch是一種能讓射頻信號通路之切換元件。常見的有SPDT, SP4T, SP6T, SP8T…等等.

常見的有機械式與電子式。

RF Switch is a component that allows for the switching of RF signal paths. Common types include SPDT, SP4T, SP6T, SP8T, and so on. And have two kinds: mechanical and electronic.

 

Failsafe(不保持型)

給電不保持,或斷電發生自動復位

Failsafe: Switches do not maintain when power is removed; they self-resetting when power is lost.

Latching(保持型)

僅給一次觸發供電即可維持訊號切換,若再次通電會從上一次通路位置開始工作

Latching: Switches maintain their position with a single trigger pulse; when power is resume and will start working from the last access position.

Normally Open

每次關機重開後,全通道不導通

Normally Open: When restarting again, all channels are non-conductive.
