希望用AWR1443 做一个单发单收鉴测微小位移的系统,想咨询下其他几个不用的通道在PCB上如何处理,是否可以直接悬空?
Chris Meng:
你好,
请参考下面的论坛讨论:

TX管脚可以悬空不接。RX管脚可以下拉到地。请参考下面的帖子说明。
The Tx pins that are not used can be left open.The Rx pins that are not used should be connected to GND through a 50 ohm resistor, we are not expecting RF transmission so a standard resistor is OK.The Rx inputs are AC coupled.
