考虑awr1243替换使用awr2243芯片，在2243手册中之发现只有2243支持Cascade (20-GHz sync)特性，这个特性具体是什么意思，难道只有2243才能支持4芯片级联，射频20GHz相参，1243难道不能支持20GHz射频相参？
从提高角度分辨率方面来看，1243必须支持相参才可能达到1.4度角度分辨率
AWR1234P支持级联，请参考下面的帖子。https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/783083/awr1243-cascade-20-ghz-sync-of-awr1243
谢谢答复
