According to the datasheet of ad9361, the isolation between RXs (including RX2-to-RX1 Isolation and RX2-to RX1-Isolation) varies between 50dB and 70dB, the isolation between TXs ( including TX1-to-TX2 and TX2-to-TX1 isolation) is about 50dB.
I have two questions:
1. How much the isolation between RX and TX ( including TX-to-RX and RX-to-TX isolation)? The datasheet of ad9361 does not provide such information.
2. How to measure the accurate value of channel isolation? Or, how the isolation value in datasheet is measured? (I have FMCOMMS3、FMCOMMS5 evaluation boards, Xilinx ZC706、KC705 evaluation boards )
