再问下:
1、where is the reflection from ? the reflection is caused by the SPDT ?
2、the wifi can be damaged , the bt chip is not ?
3、the coupler is how to work ? please follow the picture to introduce.
thanks
1: the reflection accounts most for antenna mismatching, and WIFI signal suffers from high PAR(Peak average ratio)
2: The RF path is indeed on WIFI Tx, BT chip is just on the coupling path.
3: There are several kinds of common couples. For details ,plz resort to Google. |
