接收端的傳輸線阻抗

hsuwen

請問各為資深的RD工程師
請問一下當接收迴路通過SAW後進入Tranceiver時
進入Tranceiver的傳輸線應該要保持50 ohm或是75 ohm呢?
感謝各位的指教

<P>是50OHM。</P>

refer to your TC spec.

<P>如果Design spec中提到</P><P>Rx input impedance(differential)=50-j200時</P><P>此時傳輸線仍然要用50嗎??</P>

<P>当然用50OHM线，负载阻抗通过匹配来调。不过接收端能量较小，50ohm线也不太重要</P>[br]<p align=right><font color=red>+3 RD币</font></p>
